[Eee Pad Transformer Android Development] haxin:
theres a few things that have to in place for ad-hoc connections to work. just modifying the wpa_supplicant is not the answer. first the linux kernel on your device has to have CONFIG_NETFILTER, CONFIG_IP_NF_IPTABLES, and CONFIG_NETFILTER_XT_MATCH_MAC features. These are required for tethering (ad-hoc) to work in linux/android. also binaries like iwconfig will need to be included. ad hoc connections from droid to droid are sketchy and flaky because there are so many different kernels, wireless cards, and third party apps on so many different devices. I see why so many people dont like to use bluetooth tethering. typical cellular data service data transfer rates are much slower than the theoretical limits of Bluetooth, making the potential higher bandwidth of WiFi irrelevant.

these are the theoretical maximum speeds for various Bluetooth versions

Bluetooth Basic Rate (BR) 1Mbit/s

Bluetooth 2 Enhanced Data Rate (EDR) 2-3Mbit/s

Bluetooth 3 + HS (high Speed) 24MBit/s

So on the face of it, Wifi will normally give you a faster connection however the limitation is probably going to be the speed of your phone's data connection.
[Eee Pad Transformer Android Development] timduru:
Well, what I'm trying to achieve here is connect to an existing adhoc network which would already be doing the NAT, so you wouldn't need any of that on the client tablet.

Android doesn't use iwconfig by default.

Netfilter/iptables support would be in cases you'd in addition want to share your internet connection through the tablet.

For connecting to an existing adhoc network, it mostly boils down to wpa_supplicant and the kernel wifi driver, and maybe some android-space process :)

But seeing that it times-out while trying to connect even by using directly wpa_cli commands, that should eliminate the android space process from the loop.

That should leave only wpa_supplicant and the wifi driver.
[Eee Pad Transformer Android Development] suquet.paul:
Didnt break the wifi card, but everything acted like the original file. No ad-hoc.
[Eee Pad Transformer Android Development] Seferi:
With the file i can see the ad-hoc networks around but can not connect them...

[Nexus 7 General] R3dbeaver:
So...... the internal speakers on the nexus 7 are not great. Well, IS not great. It's not even stereo with only one at the bottom making watching movies on landscape makes the sound comes only from left or right.

but anybody else experiencing cracking/breaking/distorted audio if the volume is higher than 75%?

ive never used it more than 50% coz i almost always use it at home and i have a 2-mth old baby. but yesterday i'd like to show my wife how cool the free Transformers movie is and i cranked the volume up just to be horrified by the distorted sound, not unlike coming from a cheap $10 speakers.

should i return it?

should i ignore it and just keep it under 50% for movies or plug in a nice dock/speakers?

should i attempt to fix it? :silly:

i just fear returning it as everything else with the tablet is great, and with the amount of threads here with faulty Nexus, i felt like im risking it too much.

thoughts? share ur own stories with speakers?

===================================================================

*UPDATE*

Worth a shot, rather than returning your near-perfect Nexus.

*UPDATE*

Osmo here got an APK for an app you can use to tweak if you're not as brave as the poster quoted above. thanks!

Another tips:
[Nexus 7 General] MikeMurphy:
Find someone in Ottawa on Red Flag Deals forums who bought an N7 and are returning it for defective screen issues.

Meet up with them, buy them lunch, and swap over the speakers.

PS. my audio is fine at 100%, but volume isn't exactly overpowering. In fact, there are times I have trouble hearing a person over Skype. I haven't tried Transformers, yet.
[Nexus 7 General] mgymnop:
I have the same problem. I ordered a replacement which will arrive tomorrow. If the replacement has any other issues that are worse than the crackling speaker then the replacement goes back and I keep my first Nexus 7. I might order another replacement or get my N7 just repaired after the return time expires.
[Nexus 7 General] t_007_v2:
hmmmmmmm

i have this same issue now with the cracking distorted sounds on max volume. the odd part is it just started happening on mine. see i've had the N7 since 7/18 and the sound was pure till yesterday. i thought it was or is a issue with the new kernels i have been flashing for game performance. if your N7 can be returned do it imo you have nothing to lose. N7 for the price is one bad ass tablet mate. add a nice set of ear buds and go into the music player settings under equalizer options are 3d, bass boost, 5 band eq. play with those and the N7 with the buds is going to rock playing games and watching movies. since you are going to have a clean rom root that N7 for the tablet ui and then flash it with a custom kernel to release it's true gaming power... nova 3, spiderman, mc3 are buttery smooth with the gpu set at 500 (:
[Nexus 7 General] R3dbeaver:
oh wow how hard is it to swap the speakers? as a comp engineer i know my way around a soldering iron...

hmm so u can order a replacement without sending the current one back? this is interesting.

problem is, of course, this issue seems to start the past couple of days, as i just start cranking it. what if the new one decays again after a few days? replace it again? lol
[Nexus 7 General] mgymnop:
I just got my new N7. The speaker is much much better. Still a bit distortion but only at max volume. Couldn't find any other flaw so far.
[Nexus 7 General] R3dbeaver:
super good news, bro!

yeah i emailed Google last week and last night they send me the instructions for a replacement. i requested one, should be shipped under a week, and i got 21 days to return mine to Toronto (which is 2-3days max on UPS standard).

so hopefully the new one arrives first so i can test it before i ship mine back.

yeah still abit reluctant with the whole process since EVERYTHING ELSE about my N7 is perfect. i'd rather deal with bad speakers at loud volume than cracking screen, dead pixels, or flickering....... :eek:
[Nexus 7 General] MMcCraryNJ:
I had to RMA mine for the speaker issue as well.

Turns out, the speaker is actually good, but there's a loose connection in there somewhere. How I could tell was, if I held my tablet from the bottom, the speaker would sound like it was rattling/distorted/blown. Once I removed my hand, it was fine. Watching youtube videos and moving my hand up and down the back of the tablet would result in static noises that mirrored the movement of my hand.

When I called Google, this was a known issue on some units and they'll have no problem sending you out a new one.
[Nexus 7 General] khaytsus:
God damnit, last night my speakers started rattling and now they sound like hell all the time if the volume is up at all. I believe it started when my volume got turned up too loud and a loud notification played.

So are the speakers blowing, or what's going on here? Anyone know?
[Nexus 7 General] Leukay:
Man, I have the exact OPPOSITE issue. I just bought a Nexus 7 today and my internal speaker is EXTREMELY quiet. I can barely hear it in a completely quiet room. I'd hate to RMA it since I don't seem to have any other issues with it. I tried volume+ and all it did was add a little crackling, it didn't boost the volume at all. I haven't read anything about this issue so I'm thinking defect, but if anybody has any input I would love to hear it.
[Nexus 7 General] khaytsus:
Well, I listened to some left/right test sounds and determined only my left speaker was rattling, right sounded fine. Popped the back off, and the left speaker (right from the back side, of course) was different feeling. It was looser, moved more, and was "crunchy sounding". I pushed on it experimenting a bit and it popped, then it felt like the right one. I prodded a bit more, felt the same, so I tried music.

Sounds... Better. Not perfect. Still sounds a little rattly, but might be my imagination, I'll have to listen closer later. But from this, it seems like maybe the "cone" is detaching or popping off?

I wonder what it looks like inside the speakers. I did not remove anything except the back of the N7, not the speakers, nor their little fabric covers. If it happens again, I might look further.
[Nexus 7 General] t_007_v2:
Click on settings and then on sounds. the main volume box will pop up for you. You will see three volume bars just make sure there all the way over to the right. If your volume is still real low return your N7 for one without a speaker defect.
[Nexus 7 General] t_007_v2:
I was checking out a friends N7 that just started having the speaker issue. I installed Poweramp and found the problem on the distortion. Using the balance feature only the left speaker was distorting with the right side getting very little power. How to reset the sound so both channels equal out I bet would fix the crackling sound problem. Any ideas or settings we can adjust?
[Nexus 7 General] wynand32:
I've had six N7's (yes, six, and each and every one had a significant defect), and they all had at best what I would characterize as low volume. And the ones that went a little louder have been distorted. I've finally settle on a unit that doesn't seem to have any issues other than minor screen lift and crappy speakers, and I'm keeping it.

I figured, the bottom line is that I don't use the external speakers for anything but gaming and the occasional YouTube video. If I'm watching video or listening to music on this device, I use headphones anyways. And, when I'm watching a video in some situation where I want to use external speakers, I'm using my iPad.

Short answer to your question: yes, I've had N7's with extremely low volume. Personally, I wouldn't replace it for that, because at this point the odds of getting a unit with a worse problem remain too high (at least in my experience).
[Nexus 7 General] jesseb05:
I had to return my first N7 because of the distorted speaker over 50% volume issue. I'm on my second N7 now and its been great so far.
[Nexus 7 General] happyjack96:
When I first got my nexus I tested the speakers by watching transformers. I was amazed. It was quite loud and distortion free. The next day I got a notification and all I heard was almost pure crackling. And from then on its been horrible. I use external speakers or headphones for everything but when im not using those, its very annoying. I'm not returning it because otherwise, its flawless.
[Nexus 7 General] navodwickra:
Yeah I had the same issue. It started yesterday couldn't go over 50% so I ordered a replacement . Process is really painless it will come in two businesses days and I get to keep them told one till then. Just flash the stock image band send at back.
[Nexus 7 General] R3dbeaver:
just FYI, my crackling one was C60. got the new one which is C70 and it was perfect. loud enough and doesn't crack. no distortion.
[Nexus 7 General] jarrodhinson:
I got my replacement for my 8 GB and went to the 16 GB this time from office depot. First one froze up and started having audio distortion, so far this one is doing great but only one day in. It is a c60 so hopefully that theory is wrong...
[Nexus 7 General] woshiweili:
I had my Nexus 7 16GB for exactly one month now and until today it was perfect. This morning I noticed that the speakers sounded "blown". I made sure it wasn't the file I was playing as it played fine on other devices and ALL files sounded blown on the Nexus.

MicroCenter only covers it for the first 15 days so my only option was to call ASUS. After doing a factory reset it still had the problem so now I'm sending it to ASUS. Hopefully they will either fix or replace it. :rolleyes:

This really sucks because up until this point I really loved the device. Oh and also in case anyone else is sending it to ASUS, be aware that ASUS will NOT send you anything. You as the customer is responsible for packaging AND shipping costs. I understand the profit margin on Nexus 7 is low but this is like rubbing salt into your wound. :mad:
[Nexus 7 General] khaytsus:
If you haven't shipped it off yet, use your fingernails or a guitar pick or something otherwise soft (not metal), thin, and flat, and open the case. Not sure if there's a specific place that's easier, I just went around and around until I got it to pop. Look at the FixIt breakdown if you want to see more details. It took about 3 minutes once I got it started, and that was taking my time. It's a little more firm than a phone battery cover, but not by much.

Once you get the back off, figure out which speaker is "blown" and lightly press into it. If it's "crunchy" feeling, gently work it around the edges with your finger until it either pops in place or stops "crunching". I went around the edges a few times just in case.

Been a week and my N7 sounds fine again. I have the full expectation that this isn't fixed and it'll recur, but I also doubt it's fixed in any newer hardware either, so why go through the trouble of replacing the device.
[Nexus 7 General] woshiweili:
Doh! I just shipped it off about 4 hours ago :crying:

So in other words, this problem is not caused by a broken speaker but because it somehow "popped out of place"!? :confused:
[Nexus 7 General] tkelly0727:
i have the same problem, ive had my N7 over a month and all of a sudden it developed a speaker problem, it sounds horrible when its about 60%

i have a C70 model.
[Nexus 7 General] khaytsus:
That fixed mine... It's sounded fine since. ... awkward..
[Nexus 7 General] woshiweili:
Well, it's good to know in case it happens again :)
[Nexus 7 General] fleury14:
THANK YOU!

I had spent an insane amount of time rooting / getting this the way I wanted so I was prepared to just deal with crappy audio. Took less than a minute to fix.
[Nexus 7 General] osm0sis:
No "crunch" or "pop" here unfortunately. Maybe helped a tiny bit, but still sounds bad at times after I tried working around the edges of both speakers anyway to try.

Experimenting with My Piano certain chords distort and certain ones don't at the same volume. Seems like a case of crappy speakers.. they don't constantly distort, seems to depend on the tone.

:(
[Nexus 7 General] ThePerson98:
I've got the awful blown speaker sound deal, too :( If I turn the volume up above 50%, most of the ringtones will have this really sharp crackling that I've never heard before. I didnt push the speakers hard, either. It's really disappointing, because this is my 3rd Nexus 7, and I thought it was finally the perfect one; no screen lift, dead pixels, flicker, discolorations, none of it. Suddenly the other day, I get a notification and it just has that crackling. It seems like one speaker is almost dead, and the other one is crackling beyond belief.

Hopefully the RMA goes smoothly again, and I get a device that doesn't have any issues.
[Nexus 7 General] t_007_v2:
I bought a new one 16g at wallyworld and put the blown speaker 16g in the box and returned it. I'm very careful with the speakers on my new one. I use headphones when gaming and never have the volume full blast. I plan on buying a i-tour portable speaker for my little beastie n7.
[Nexus 7 General] R3dbeaver:

Noozxoide EIZO-rewire PRO 3rd Party Equalizer is designed for tablets: http://play.google.com/store/apps/details?id=com.noozxoidelabs.eizo.rewirepro

Might help us to avoid frequencies that rumble, and bring out some clarity.
[Nexus 7 General] R3dbeaver:
link not found...
[Nexus 7 General] osm0sis:
Indeed. They pulled it. Nevermind I guess. :p
[Nexus 7 General] osm0sis:
Looks like Noozy got taken down because it was a modified redistribution of an older build of ZPlayer, without permission. Not sure if that's where Rewire came from too or not, but maybe the whole developer got kicked off. :(

Edit: Rewire seems to be the part they made themselves which they added onto the old ZPlayer code to make Noozy ("New Z" ;)), so it should be safe to repost. Attached as well are my Equalizer settings which seemed to make the most difference, removing the rumbling/distortion almost completely.

My settings are as follows: XLimiter enabled, compression strength "Hard"; Psychoacoustic disabled; X-EQ enabled, frequencies at -1.0, -2.5, -5.5, -2.5, -1.0; VE-Engine disabled; Logicsurround ES enabled, room size "Studio".

Hope this helps some people! :)

Edit 2: New version up on the market for a limited time - https://play.google.com/store/apps/details?id=com.noozxoidelabs.eizo.rewirepro

I'll attach the final version for convenience if they take it down again. They say they'll have a new, professional "VSP" available sometime in December, but this EIZO version will remain freely distributable. :good:

Felt the pop but failed

I noticed my nexus 7's speaker's issue this morning and I was really excited to find this post about the fix. The back of the case took some time to open but not a major issue. Found the right speaker to be the problem and pressed on it till I felt the pop. Tested the speaker right afterwards and the same problem persisted; crackle/pop at high volume. I suppose it's time to send for repair. Anyone who did send it back for repair/replacement, can you give me the info for that? Thanks!

I just found on Asus website that the only tablet service is in PR?! Did everyone who sent for service sent your tablet to PR for repair?

what in the hell are you talking about....? did you just throw some garbage to Google Translate and came out with that? :laugh:
[Nexus 7 General] osm0sis:
I think the poor guy relies on Google Translate for English. :(

Also, when I first got my N7 I did pry open my case and push down on the speakers as per the OP, but there was no popping or snapping in place.. So I figured there must also be a bit of resonance we have to deal with to avoid the distortion/rumbling, and now we finally have a nice EQ to help. ;) :good:
[Nexus 7 General] madcook:
Are the flaws as bad as it sounds .I want one bad should I still buy it or not?
[Nexus 7 General] osm0sis:
Buy one. No regrets here. Return policies exist for a reason in case you get a real lemon. ;)

Mine had lifting issues and notable distortion/rumbling with certain frequencies on the speakers. Popped the top, adjusted some screws, moved the foam spacer to a a lower surface and pushed in the speakers to make sure they were seated as per the OP. Fixed the lift but the speakers were fine but still distorted. Then the EQ I posted on the last page came out and now my N7 is perfect. :good:
[Nexus 7 General] speedwaystar:
as per the OPs instructions, I pressed on each speaker until it popped down. aha, I thought, problem solved.

except that, now I have no sound at all. peeling off the speaker foam reveals the speaker membrane which seems to be concave where before it was convex. is it possible that by pushing to hard i have forced the membrane down onto the electromagnet preventing it from vibrating?

assuming that I buggered things up by pressing too hard, is there a way to get the speaker membrane to pop back to its prior position?

cheers,

Bernard.
[Nexus 7 General] osm0sis:
You were supposed to push on the rims, not the actual speaker... :(

[Nexus 7 General] osm0sis:
The original post by khaytsus does say "work around the edges" multiple times, but hey, it never hurts to repeat it a different way if it keeps people from breaking their devices. :eek::fingers-crossed:
[Nexus 7 General] speedwaystar:
does anyone know enough about how this kind of speaker assembly functions to suggest why pressing down on it (gently) would cause it to stop working?
[Nexus 7 General] R3dbeaver:
im no engineer, but try opening the wikipedia page of "speaker". it's basically a thing that convert electrical waves into sound waves by vibration. press a speaker too much and you'll stop it from vibrating.no vibration, no sound.

edit: just saw your original post above. yup. press it til it concave instead of convex will screw it up coz now its too rigid to vibrate and/or you push it until it touches the inner "membrane".

if you can pop it up again u should be able to fix it. should.

if not, u can replace it with Google, or if ur crafty enough, go to your local electronic store (the ones college/engineer students go to, not best buy)(at least radio shack) and buy a replacement speakers. dont kno the spec but i heard the ones from other tablet works fine.
[Nexus 7 General] speedwaystar:
cheers. I'll probably end up having to replace them then. for those interested, http://iFixit.com has a good Nexus 7 teardown guide which includes removing the speaker assembly.
