Hi and thanks for reply. I looked at the DAC you use and read through that link. Another good thing about the external DAC is any analogue ground noise from the device should be isolated. There is ground noise on this units RCA outputs (to be expected on a device in this price range) once you rig up the bluetooth/radio via rca's anywhere into the chain that noise will be re-introduced. I'm not sure there's a way round this issue but its a minor one.

The HiFimeDIY also has spdif out so if connecting to my DSP with digital coax I assume the volume pot wouldn't work? Not a problem since any DAC will have it own analogue volume control I can use the master volume (after DSP). Still if I connected BT/radio via RCA that volume would be controlled by the device. Unless somehow I set everything up for max volume and use just the master to control everything. I have a lot more learning experimenting ahead!

This could be a deal breaker:- Will spotify ouput be routed through the DAC?
[Android Head-Units] gtxaspec:
Yes it will.
[Android Head-Units] mamba76:
Thx GTX its got be worth pursuing then:)

The model of my unit is AE0273B on autopumpkin. Does anyone know for sure that BT/radio/DAB wouldn't be routed through a USB DAC? Would be interesting to know why?

Should I be looking to root this so I can have Viper4Android installed or Neutron player? I just want to unlock the potential for quality audio out, I dont need to tweek the signal or colour it I would like the output flat but a good PEQ app would be helpful.

Using a multimeter and oscilloscope I swept a pure 0db sine wave through the Alpine and the AC voltage from the pre-out only deviated by about 0.01vac from 30hz upto 10k then it climbed a bit more. Done same thing on the Pumpkin and highest unclipped Vac is 1.2vac at 1khz, at 30hz it dropped to 0.5v and same with higher frequencies, just like a sad smile lol. I want a DAC with a flat frequency response and a 4volt pre-out.

The floor noise / ground noise was made worse because I had to increase input gain cos of the crappy pre-outs.

I could do with some help customizing this for quality audio so if anyone's in the same boat and wants to trade ideas Im open to test things on my device and help out where I can.

what apps & DAC's work for you? digital or analogue cabling? What DSPs? Anything regarding SQ is interesting to me :D

I think Iv taken one step forward and 2 steps back but I'm committed now lol.
[Android Head-Units] mamba76:
Just found and read through this thread - https://xdaforums.com/android-auto/...io-problems-discussion-thread-t3657637/page11

Aluver seems to be able to fix this issue.

The pumpkin is still a great bit of kit for the price and to be fair I used the buggy built in amplifier app to adjust the eq to a V shape, pulling down 1khz (in the middle)as the lowest point (-6db) and as no surprise I think this has cured the problem this HU caused with the SQ. At low volume my target curve in REW appeared the same its only at high volume when the pre-amp output deviations are at their most extreme (sad smile) which is why it sounded too harsh.

Im really not sure if I would be able to tell the difference from a 100% digital system with high quality DAC and my old alpine setup but it does solve a few problems.

Still have excessive ground noise and amp pop when ignition turned off (never had before) so not sure if Ill be keeping this unit, so maybe up for UK sale in near future!
[Android Head-Units] Hypnox99:
Really interesting thread, are you planning to buy the DAC finally ? It would be interesting to try a DAC, just to get rid of the ground noise for example.

Seeing your setup, if the source has crappy output you will hear it right away so your EQ modification is quite surprising that it improves the quality that much ! I'm still thinking about pulling the trigger on a model similar as you but very afraid of sound quality. Still trying to decide between Joying Intel or Xtrons PX5 :)
[Android Head-Units] mamba76:
Im going to give it a bit more time to see if I can get it to behave. Iv has this set up with the alpine for a couple of years and am always tweaking / improving so Im very aware of any change. If it hurts your ears at high volume then somethings wrong. The alpine's FR was completely flat and clips just over 2v, the pumpkin clips at different voltages (max 1.3v) but on this unit anything above vol 20 with pure tones will clip, its just a pain in the ass but if you always eq your car with high volume in mind for me that's where it matters. Dont rely on tone generator apps their 0db is not accurate I burnt the test wave files from JL audio website to CD as a reference then match it with Room EQs generator so can sweep any frequency.

Yeah Im gonna look for a DAC would be nice if you could control the DACs volume from steering wheel! And the auto switching rca's it doable or might as well go digital to dsp not sure yet its all a bit of a headache lol, but the units capabilities makes it worth trying. I will post any solutions on here if I find them but may be some time.

Im still trying to work out what this unit gives me that an alpine ilx-f903 (or similar) won't, apart from alot of spare change!

Im sure Iv read pros and cons for either them units but don't know enough about whats inside. I know mines a px5. I would be looking for something that can output everything through USB but not sure it exists.
[Android Head-Units] mamba76:
ordered a minidsp usb streamer from amazon £60 delivered +van damme digi cable. First step see what it does out of the box then install 'USB Audio Driver Pro' app which will bypass the native android drivers??

I think this requires usb debugging mode to be enabled in developer options.

I found a switching module that might come in handy - https://www.tindie.com/products/Beni_Skate/automatic-spdif-opticalrca-audio-switch/#product-reviews

If anyone understands what Im trying to do and can foresee what needs to be done regarding operating system changes I would definately appreciate any advice as Iv no experience at all with the programming side of things i.e changing audio policies, etc...

I should be playing with this again at weekend if all the bits arrive :D
[Android Head-Units] mamba76:
Hi RoNeReR. I see your usb dac outputs on analogue rca's. Do you still control the volume from the pumpkin?

Thx
[Android Head-Units] mamba76:
Well as promised I will update this thread with my progress to get my system setup with the pumpkin.

I got my mini streamer but digi cable not arrived yet.

So I enabled developer options which was easy but couldn't find the menu anywhere afterwards, eventually downloaded an app call 'developer options' which does what is says on the tin. I found usb debugging mode was already on then went to 'usb configuration' and set to 'Audio'. Plugged in my ministream and was expecting the audio from spotify to go quiet as is should now be trying to route through the streamer but it didn't appear to change anything. I get a feeling when I eventually get the cable and connect to the dsp I will still have nothing. Anyone know what else I need to do to make audio goes through USB? ASIO drivers?

As I said Iv no experience with android OS but Im learning more and more things, so happy days!
[Android Head-Units] gtxaspec:
The problem is the software and hardware combination needs modifications (software) to generally work. We have this working on the joying Intel, and hopefully soon on the joying px5 (FYT based) units. Nother brands might not be possible depending on the original manufacturers programming.

If other users with your unit, maybe they have experience. Generally only working on the joying with Xposed properly.
[Android Head-Units] mamba76:
I see. I read a post where 'Aluver' says he got usb output working on app media and usb fobs but not on BT/radio/DAB (which went throught the MCU instead of DAC?) so assumed it was doable with a few changes to audio policy. Thinking about it not sure if the thread was referring to my HW/SW. Ill read the thread again but got lost in the jargen which I half understand.

So it looks like I'm just gonna have to wait till someone works out a fix.

So PX5 is the hardware and Oreo the software. Whats FYT based? Can this unit be rooted easily yet?

Thanks
[Android Head-Units] mamba76:
Are there any car android devices out there, chinese or otherwise, that allow for routing ALL audio digitally?

Any HW/SW setups know to work?

What about the latest 'NewsMy NR3001'?
[Android Head-Units] gtxaspec:
FYT is the OEM manufacturer for the system on module (SoM) that powers certain head units (that contains the CPU and memory etc)

Px5 is the CPU made by rockchips.
[Android Head-Units] mamba76:
Whats the model of Joying intel you have working? I assume there is still the problem of bluetooth / voice & radio still not being routed through USB on this as well?

I connected my XP laptop to the ministreamer then to DSP (with vanne dam spdif coax) and played some flac files and it sounds great, noise floor is zero! Shame I cant find a device other than my phone to output a dam digital signal for everything!:crying:!:mad:

PS: Android 8 Oreo + all extras for sale... £200 anyone?? (comes with dabonwheels DAB external whip aerial, original in dustbin) Will drop in a B6 / B7 Audi A4 like factory does.
[Android Head-Units] gtxaspec:
I have the joying Intel that fits into the b7 a4 as well. On their site, and yeah no radio or Bluetooth yet via dsp.
[Android Head-Units] Hypnox99:
Oh too bad :( you can't even get the spotify output on the dac? Did you try another dac like hifimediy using optical cable?
[Android Head-Units] mamba76:
Thanks for the info gtx.. You know a hell of a lot more than me on these things. If you could suggest a head unit thats a safe bet for what Im trying to do Id appreciate any links / model numbers. I bet there's more than one joying intel out there and dont want to make the same mistake twice:eek:
[Android Head-Units] mamba76:
Hi. its not the dac thats the problem its that no one can get the output through the usb cable to start with. At least not yet but sure some very clever ppl on here will figure it out:fingers-crossed:
[Android Head-Units] gtxaspec:
What car do you have???
[Android Head-Units] mamba76:
GTX, Iv just read some of your page about your custom ROMs. I didn't know that your obviously an expert with these. I don't know enough to ask any legitimate questions yet. It seems these chinese based units are being produced on mass, some with more capable hardware most with buggy / rushed/ inferior programming of the operating system so developers like yourself can create customized improved changes to the operating system and changes in the kernals that can for example 'route audio through usb' :) but only within the limits of the hardware.

Do you mainly deal with Joying units or are there other models / brands that offer better more versatile hardware configurations or is it that Joying are the best platform to date?

Cheers

[MENTION=382164]GTX[/MENTION]

I have a B7 a4 3.0tdi (now with double din cage)
[Android Head-Units] mamba76:
Iv spent so much time looking into different head units, brand names and no-names.

If I plug minidsp's mini streamer in the USB socket on my old XP laptop I get a perfect digital signal out for all audio. Its just plug & play. Volume control at source, Its simple, it works, its just a computer. Excellent. Why on earth in this day and age can't we have the same thing in a car!??

Alpine offer optical out on some DD models - cant control volume from source

Clarion (only one that makes 'digital output' known on their marketing) - hdmi output same issue in volume control

Chinese androids - not all audio can be output through USB. None are plug n play (all require modding of the kernal to achieve this)

Not one manufacturer offer spdif coax output or USB audio streaming.

This is like when alpine finally added a usb input to their head units 10 years after the tech was out (first one featured in the film 'super bad' I had one)) or the world after concord!

gonna stick my old single din alpine back in until the tech is available and use OTG stream for my S7. Spent too much time on this already.

I have this 2 week old unit for sale - £200. inc. better DAB aerial, install scratches on side of cage not on screen! camera & obd2. - Uk only - London SE. PM me if interested.
[Android Head-Units] expo1122:
Did you ever solve this? I have the pre out hissing sounds also. I may try to use the high level inputs as i did not get any hissing when i had speakers hooked up to the built in amp of the head unit. Another option is to use bluetooth output to an amplifier or DSP but not sure what kind of quality would be there. It would most likely eliminate the hissing
[Samsung Galaxy S9  Questions & Answers] jporter12:
SO yeah, I've seen where people have had software issues causing this on the Note 8, and S8 models, is it a bug that crept into the S9 as well? The tech at the Sprint store verified the cleanliness and dryness of the port, thinks it's the port, and they won't have parts to fix it for probably a month or so. I REALLY don't want to send it in to be fixed, so I bought a couple wireless chargers.
[Samsung Galaxy S9  Questions & Answers] DeadlySin9:
It it showing constantly or only when a cable is plugged in? If it's with a cable, have you tried other cables? I had my phone give me that message earlier today when plugging in an incompatible hub. The hub wasn't even connected to anything.
[Samsung Galaxy S9  Questions & Answers] nabbed:
Have you checked with your wife?
[Samsung Galaxy S9  Questions & Answers] spampa:
Have you tried to reboot the phone? I'm not kidding.

Let me know ;)
[Samsung Galaxy S9  Questions & Answers] jporter12:
All the time. It has a popup with sound when you plug it in. The rest of the time, it's just a notification in the tray.

Yeah, tried rebooting, wiped cache, power down all the way, multiple times. Tried plugging the cable in while booting. It looks to be charging while plugged in and powered down.

So, the message went away, and it would charge with 2 different chargers, normal speed, not fast charge. Would not work with a charger I have here at home. None are Samsung chargers, but all are QC 3.0, which will report as fast charging on the phone. Then today it charged fast in the truck, and the one at home works, but only slow speed.

I'm not going to stress over it as long as the fast wireless charging keeps working. The battery life is more than enough to get me through a day, and I'm ordering stuff to integrate wireless chargers into the vehicles.

Thanks for reading and trying to help!
[Samsung Galaxy S9  Questions & Answers] spampa:
I probably missed to ask before, but are you sure you are using the original cable, together with the original power charger?

As stressed by [MENTION=4826098]DeadlySin9[/MENTION] the problem may be the cable. Try other cables.
[Samsung Galaxy S9  Questions & Answers] jporter12:
Yeah, I had tried the original cord and charger. whatever it was effected the phone before even plugging it in. The message would be there in the notifications, then plugging the cable in would set off an "alarm" telling me to unplug it and let it dry.

A couple weeks later and it is working just fine, charging with pretty much any cord, and charger. Ugh. I hope it stays that way! LOL At least Sprint DID give me a pretty good discount on a 2 pack of wireless chargers, which is what I use most of the time, now.
[Samsung Galaxy S9  Questions & Answers] spampa:
Thumbs up!
[Samsung Galaxy S9  Questions & Answers] swami07:
So, I've had this problem with my new Galaxy s9 as well. Here's the specifics - this only happens IF the phone dies from running out of power. If I let the battery drain on accident, I plug in the device...new cord/charger, original cord/charger, doesn't matter...and it shows the charging symbol for just a second, and then warning there's moisture in the charging port. There's not... If I set the phone on top of a wireless charging pad for a few mins, it charges just fine.

All I have to do is get 3 - 4 % so I can power on the device and get to the home screen. If I can get to the home screen, I can plug the phone in with the cord/charger and no problems.

I just did a warranty replacement because this problem is real annoying. I don't let the phone run out of power often, but sometimes when I'm traveling for work or camping with scouts, it happens. So, before I sent my old phone back for the warranty swap, I let the new phone run out of power and then tried to plug it in. Same error!!

I just got this Hizpo 6.2" inch Android 7.1 Double Din In Dash Radio.

According to the manual, this unit appears to support Ipods, but I can't find any info on it

It has a port on the back for a wire harness also after enabling it in the factory settings, it adds a Ipod icon to the app drawer.

Does any have any info on this or know where to get a wiring harness?
