Asking for help from anyone who has a 5.1 audio setup to his/her PC.

At issue is ffmpeg's bug in incorrectly mapping channel order from AC3 (and perhaps other formats) to AAC. Before, you had to remap the channels using an intermediate app like sox. But my current testing (on a 2-speaker setup) shows that there isn't an issue. Confirmation from a 5.1 setup is needed.

Attached below are 4 audio test clips: 5.1 WMA, 5.1 AC3, 5.1 AAC (from WMA clip), 5.1 AAC (from AC3 clip). The clips tell you which channel the sound is supposed to come out of, eg "front left".."front right"..etc. The LFE channel will be a mumbling sound coming out of the subwoofer.

I would appreciate it if someone with a 5.1 audio setup would test all 4 clips, and tell me if the channel orders are correct for all four. The clips are only 9 secs long apiece. Thanks in advance.

Someone sent me a PM asking which build of ffmpeg I'm using (for the correct AC3->AAC mapping). Not sure if I sent a reply, so I'm cc'ing a copy here.

I'm using the Zeranoe build. This is from AC3 to AAC. I didn't test the other way. (If one way comes out OK, the other should as well, but you never know.)

I am running FRX07 on RHOD210 using HaRET. Phone reboots after 5-10 minutes. I observered that the reboot happens mostly when the phone sleeps. If I keep working on the phone (listen to music etc.) then the reboot does not occur.

I have placed the latest kernel (7/18) and the rootfs as well from the incremental updates link.

Please advise.

I am booting off a Class 4 Micro SDHC Sandisk card. Tried various version of android like FRX07, NeoFroyo but the same result.

Hello,

I'm new here.

I just ordered the SGT here in UK and I was curious to know if it is possible to use bluetooth headphones and normal headphones at the same time.

I'm asking this as I will be using my tab on a flight and I'd like to watch movies with my partner.

I know I could buy a 3.5 mm jack splitter but I'd like to use the bluetooth heaphone and one 3.5mm headphone.

Did anyone try this?

Thanks

I've tried it before on other Android devices, and it wasn't possible. I doubt it is now. Wouldn't it be easier to check than to ask online?

Hello,

When I try to unlock my Desire I have a problem. I press the power button, and the screen flashes on, and then straight off again. The keys at the bottom are still lit and I have to press the power button twice before I get the unlock screen up again. SOmetimes I only have to do this once, but sometimes I have to do it many, many times before I can unlock the phone.

I have tried using different lock screens, different options etc but they all seem to have the same problem.

[Galaxy S II General] zelendel:
You need to keep it under a set limit
[Galaxy S II General] doc1964:
if your message works out to be more than three standard sms messages in length then it automatically gets converted to an mms message. I think that the app handcent for messaging allows you to get round this. I kow it is unfair as most phone packages have free sms but you pay for mms.

Howto compile the kernel yourself

Compiling this kernel yourself is not very hard.

1. Set-up chulri's development enviroment

2. Configure the new kernel

[Shell] cd $ARCHOS

[Shell] make kernel-config

[Config] In Networking support -> Networking options -> Network packet filtering framework (Netfilter)

Core Netfilter Configuration -> Netfilter Xtables support: y; Xtables -> "owner" match support: y

IP: Netfilter Configuration -> IP tables support: y; Packet filtering: y; REJECT target support: y; LOG target support: y

[Config] In Filesystems

The Extended 4 (ext4) filesystem: y

Ext4 extended attributes: y

[Config] save changes and exit

[Shell] make kernel-build

After compilation, locate your kernel zImage and flash it together with chulri's initramfs.cpio.gz (which is also provided in the zip in the first post).
[Gen8 Android Development] WhoDunnit:
Recommendations to speed up your tablet

Now that you have your Archos Gen8 as you want it, I can recommend two additions to speed up your system.

1. You now have a fast, big ext4 data partition which you should use for all applications:

[Shell] adb shell pm setInstallLocation 1

2. Replace the default Launcher *ANY* launcher but the Archos one. Personally I recommend the Zeam launcher, since it is really lightweight:

Get your copy of zeam, install it, press "home" button and make it default to zeam.

[ADB] su; cd /system/app; mv Launcher2.apk Launcher2.apknot

The last step makes sure that the Archos launcher does not startup anymore, saving your memory. The last steps also removes the default Archos wallpapers, so make a copy of the one you want or get some nice new ones.

Since the device setup of this thread uses unionfs to make changes to the /system, you could also just remove /system/app/Launcher2.apk. To restore it you can remove /mnt/system/unionfs/system/app/.wh.Launcher2.apk. (Thanks to skeeterfood for pointing it out.)
[Gen8 Android Development] chrulri:
Great work! Thumbs up! :cool:
[Gen8 Android Development] AlaskaPardus:
Thanks for this awesome tutorial!!!!!!

Thanks to all the people who work on our Archos Gen8 devices!!!!
[Gen8 Android Development] cHarOn99:
is the performance comperable to urukdroid? i really like urukdroid but the mediascanner issue drive me nuts :D.

Anyway great work and thanks for the tutorial, now a kernel to be able to overclock and it would be awesome :D :D
[Gen8 Android Development] WhoDunnit:
I don't know if performance is comparable to UrukDroid; I've used Uruk 1.0 for some months but I haven't run any benchmarks. The reason for that is that Quadrant keeps giving errors in fixed landscape mode and I always used fixed landscape because the stock Archos launcher takes for ever to redraw on screen rotation.

Now of course I replaced the Archos launcher with Zeam, and now redraws on screen rotation are very fast. Replacing the Archos launcher in UrukDroid with Zeam would of course give you the same improvement. Anyway, with the configuration described above @800MHz (I could set it at 1GHz but I didn't) I get Quadrant scores of 1810. If you run it on UrukDroid, we can compare.

Definitely my system is booting much faster now than than it did before, but that might just be Zeam.

Right now sibere is making kernels for UrukDroid which give a nice performace improvement; perhaps he is willing to make kernels for stock too, or help me a bit along? Also when I have some more time, I hope to port some of Ardatdat's kernel improvements to the latest firmware kernel. Maybe someone else is working on that already?
[Gen8 Android Development] VU HEO:
I agree with you, Zeam is the best Launcher for Archos . When installing UrukDroid, my Archos is longer battery life, LCD is more sensitive and it very fast . Another devices, when you increase speed of cpu, battery life is softer .

I don't think Uruk firmware had been cooked with stock kernel, stock kernel's not stability.
[Gen8 Android Development] cHarOn99:
thanks for the reply, personally i don't care about quadrant which is the worst benchmark at all :D, you already answered the question good enough for me, you said booting is faster and general the feel is fast, thats for me a better benchmark result then any syntetic test which gives you results like in the lottery :D.

I use Golauncher on the A43 and it works also good, i never used the stock launcher :D.

I think i will try your solution out and look forward to some kernel improvements if you make one, if not then also fine.

Thanks again
[Gen8 Android Development] AlaskaPardus:
i prefer VTL.Launcher. it is based on adw, but better configurable. i remove ALL soft buttons, all panels and the notificationbar. instead i use Button Savior to have HOME/BACK/SEARCH/MENU buttons.

runs pretty smooth and i can use fullscreen.
[Gen8 Android Development] WhoDunnit:
any launcher goes

Right, that's the beauty of android: Anything can be replaced and modified to your own taste. I modified my recommendations above about replacing the default launcher with Zeam: *ANY* launcher is better that the Archos default one. My only reason for recommending Zeam is because it is lightweight.

Bottom line: replace the launcher with any alternative and you will have a smoother system.
[Gen8 Android Development] AlaskaPardus:
I love open source and, of course, linux(android) and the power of freedom it has. i hope it will never become mainstream as Windows or Mac is.

Thats the reason why i donate as much as i can to oss projects instead buying expensive Windows software.

And thats why i have big respect to all people who made our computerworld a little bit better to use! Call me a idealist, i am proud to be one! If we were no idealists things like Android wouldn´t exist.

OK, enough ;)

back to topic!
[Gen8 Android Development] skeeterfood:
Might as well just do:

[ADB] su; cd /system/app; rm Launcher2.apk

since it's really not deleting the file, but instead creating a .wh.Launcher2.apk file in /mnt/system/unionfs/system/app/ that causes unionfs to hide the file. You can always get it back by removing the /mnt/system/unionfs/system/app/.wh.Launcher2.apk file.

Is the ext4 1 gig of data for extra app space?
[Gen8 Android Development] WhoDunnit:
Right, thank you. I added it to the steps to follow.
[Gen8 Android Development] WhoDunnit:

Thanks for all the work. Looks great and I'm about ready to try it but need to know first, will this work on the A70H (250gb version)?
[Gen8 Android Development] Harfainx:
It's been suggested that you shouldn't perform this operation on the hard-drive versions. Constant app re-writes on the hard-drive could be a cause for early drive failures.

Nice write-up here WhoDunnit. I did a Windows-based write-up last month over at the ArchosFans forum. Now it looks like people have some options for methods to create their partitions on both Linux and Windows. More information is always a good thing :D

http://forum.archosfans.com/viewtopic.php?f=76&t=54637
[Gen8 Android Development] WhoDunnit:
OK, great. I added a link to your thread so people can find answers if they want to do this from windows.
[Gen8 Android Development] WhoDunnit:
Well, they use the same kernel so I'd expect it would work (though I haven't tried it myself, so no guarantees ;) ) However, as Harfainx says the extra ext4 partition on your harddrive may affect your harddrive life. The iptables stuff should be fine though.
[Gen8 Android Development] akmalhisyam:
will this method works for 2.4.19?
[Gen8 Android Development] WhoDunnit:
Don't know yet; if Archos has updated the released kernel sources then method should enable you to compile the new kernel yourself. work again. You can NOT use the binaries for 2.3.81 of the first post together with firmware 2.4.19.

Cannot update them right now, will do so soon.
[Gen8 Android Development] menshen:
Please, I need some help...

I updated to version 2.4.19, and I followed the instructions on post 1.

I rooted succesfully following chulri's method, and I repartitioned Archos, but when I change init.rc from "mount ext3 /dev/block/mmcblk0p4 /data noatime nosuid" to "mount ext4 /dev/block/mmcblk1p2 /data rw noatime nosuid nodev barrier=0 data=writeback nobh" and reboot, I got message "low on storage". Application app2sd said to me that system storage was 228 MB and 2 free MB, instead of 1GB.

What is the problem? With version 2.3.81 it worked perfectly...

I think that mmcblk1p2 is not pointing to 1GB partition in 2.4.19...

Thanks in advanced!
[Gen8 Android Development] WhoDunnit:
I haven't update to 2.4.19 myself yet, so I cannot know for sure, but my guess is that you used chulri's 2.4.19 zImage and initramfs. These do not have ext4 support, and that's why the 1GB partition is not mounted.

I don't know if the kernel sources have changed between 2.3.81 and 2.4.19. Chulri should know, but he's on a holiday right now. What you could try is, to flash my 2.3.81 zImage and initramfs as attached to post 1. In the worst case you cannot boot your tablet anymore but you can fix that by reflashing with Chulri's 2.4.19 zImage and initramfs, which will bring you back to where you are right now.

Good luck.
[Gen8 Android Development] menshen:
Thanks for your reply, WhoDunnit

Yes, you were right, I was using Chulri's zImage and initramgs. I tried to use your zImage and initramfs (from post 1) but it does not work...

So, are you planning to modify your zImage and initramfs according to 2.4.19?

Thank you very much
[Gen8 Android Development] WhoDunnit:
Certainly, as soon as I get my hands on the new firmware/kernel sources.
[Gen8 Android Development] paultamhk:
Hi,

Previously I resized the parition to ext4 in 2.3.81 and updated to 2.4.19 and everythings works fine.

The only things to do is you first update the stock fw, then use Chulri 's initramfs and the customized kernal file (Zimage) mentioned on post#2 to flash in DE, then you will see the ext4 partition again in 2.4.29 fw.
[Gen8 Android Development] menshen:
Yes, it works! Thank you very much.
[Gen8 Android Development] WhoDunnit:

hello WhoDummit,

i have an Archos 70 IT for a while now, i like it so much because i can do a lot with it and i take it everywhere and i think the size is great because i can put it in only 1 hand easily (it will not be possible with the gen9).

During this time, i have found only one thing, the lag problem, but more specially the little memory size ! I have study the CPU and i use it to 1Ghz less than 20% of the time, but for the memory i must always clean it. To solve partially the problem, i have replace the launcher by Zeam and the result is very good, but for the memory, i think that android is not manage it correctly, apps are in stand by in back ground and the device lag quickly if you don't empty the memory regulary.

Have you a piece of advise to this ?

If i install your kernel, i will have EXT4 for the apps & data, but it is so different compare to EXT3 ?

Best Regards

Mister S
[Gen8 Android Development] WhoDunnit:
I cannot say I recognize that lag problem, so no advise from me there. Probably due to some memory hungry applications (games) you're running?

You can use my kernel with ext3 if you prefer, just make sure you put "ext3" in the init line then.

The benefit of ext4 is speed. Benchmarks I have seen all indicate that ext4 gives a significant boost in disk I/O, which you want because with my setup you will be using your internel sd for apps, caches etc.

Hello dear WhoDummit :)

i have done all the step from post1 (format A70, install FW 2.4.19, install kernel Chulri's 2.4.19+RW, install your kernel from iptablesext4_2.4.19.zip, repartition my internal storage whit Gparted live CD to create a 2GB partition in EXT4, modify the INIT.RC (at this step i have correctly have a second startup wizard) ) but i obtain the same pb as above => I got message "low on storage" and 2 free MB, instead of 1GB.

Please help me, i don't understand, i do it all step carrefully, i redo the all thing 3 times, and 3 times the same 2 MB free space :(

Best Regards

PS = i have an external SD card in my A70 in addition of the internal storrage split in 2 partitions (6Go FAT32 + 2 Go EXT4), may be the system is mixing partition between intarnal and external when mounting
