Hello! Previously I had cheaper android HU, not MTCE unit, and had no noise in speakers. Now I bought PX5 DSP and there is constant static noise in speakers. Pretty loud. But static, so nothing changes it. Tried disabling LCD, buttons backlit, and nothing helped. Tried using DSP, nothing. Making louder or quieter does not change pitch or volume of noise. Volume on 0 cuts off speakers so there is no noise. Booting up the radio, noise comes after launcher load.
I have BOSE system in my car but as I said, neither factory nor my previous HU made any noise.
Is it possible to track the source?
You might have missed the many other posts about this known issue.
What did the reseller suggest when contacted for support?

So there is no sound in my infuse. I have looked other threads and at least their headphone was working so speaker must have lose contact.
In my case not even headphones, mics, in call sound etc nothing works. Anything related to audio does not work. Headphones get detected, ie when i try to raise volume it suggests high volume can damage ears, but no sound through it.
It happened to me twice before and once it worked after few days, and the second time i twisted my phone a little and sound was back on. Now i tried everything, opened up removed the speaker and reinserted, straightened out the speaker audio pins and all but no result.
So if audio does not work, nothing works not even headphones or incall mic. What might be the problem?
Hi everyone. I'm new to this forum.
I have a stock Moto G 2015 2/16 GB version.
I've always had a problem with it: when I try to play an audio clip in Telegram or Whatsapp through the earpiece speaker, by pulling the phone up to my ear, the volume is just too low. It's all right if I'm in a quiet room, but as soon as there's even modest noise around, I can't hear anything. I can use the volume keys to adjust it, but it turns out I'm already at the highest setting and it's definitely not enough.
Conversely, when I use that same speaker during a phone call I can hear fine, even in a noisier room.
I'm running Android 6 at the moment but, as I said, I've had this problem since the beginning, when my phone still ran 5.x.
Thanks for any suggestions.
I actually have the opposite issue.
xt1540 2/16 6.0 stock not-rooted, bootloader unlocked
Music audio, notification tones (bells,beeps,whistles) are fine and loud
Phone calls volume is very low.
I've tried...when call starts down the volume then back up...no go
Move back to 5.1.1, still same issue.
Tried removing LCD to get ear screen out of the way...still issue persists.
edit > 4-Sep-2016
I replaced the ear speaker, still low audio during calls. I forgot to describe when call is placed in speakerphone mode, the audio is fine albeit slightly distorted on high volume.
** comment ** I have a Lumia 640 LTE, (SD410) call volume in earspeaker is loud where I have to turn it down a couple clicks. And I've had people tell me that on their end my voice comes through same if not better than a corded landline. (using the same SIM that was used in the G3).
squid kernel screws the speaker while calling, make calls louder
Looks like it's an issue with a lot brand/model phones.
Something about mixer_paths.xml and "RX1 Digital Volume" needs to be changed.
So I'm guessing all the manufacturers are really lazy in tuning their Android smartphones to perform best for it's primary function, being a phone. Well, for that matter, overall sound quality with all the mic's and speakers.

Thank You hp420
I haven't tried it yet, but when I do I'm sure my G3 will be usable. And thanks again for taking the time and testing/providing different volume level versions of mix_paths.xml.

Update: I've tried the modified mixer_paths.xml, only marginal success. Possibly have a damaged speaker.
I have just installed an Erisen 7591-HA (PX5) into my 2010 Golf Gti and I am getting static and digital processing sounds through my speakers.
If I mute the head unit there is no static or other sounds.
The digital processing noise happens when playing music via usb and Spotify when selecting the next track.
This is my first Android head deck and I am really disappointed.
Sound is going through an Alpine PDX-F6 amp.
I have tried disconnecting the radio plug and removing the head unit from the dash but no change still has static and processing sounds.
Sound issues remain if the engine is off it makes no difference.
Static and digital sounds do not increase with volume, it remains the same no matter what volume it is at unless the head unit is muted.
Good quality RCA and speaker cable was used.
Any help would be greatly appreciated.
I have the same issue with a Belsee unit I installed last week. Do you have a line-level filter in your harness? I have a theory that the line-level filter that's included in mine is unnecessary, as it's coming straight off where the RCA outs would normally be (and those are line level already, right?).

No I do not have a line level filter on mine.
I have tried using an RCA GROUND LOOP ISOLATOR but this done nothing.
Below is a link to the sound I am getting from the head unit, you will see it only makes the sounds when volume is not muted.

Same issue on my PX5 KGL unit, not tested with filters or similar...
I read somewhere that the LED color-changing caused interference - and I noticed that you have yours setup that way. Have you tried setting a static color? Also, make sure all of your wiring is clean and try to keep any speaker wires away from any power wires (although that is more applicable to an external app setup).
Can you hear the noise at all while music is actually playing? Obviously, it would be better if it wasn't there are all, but if you can't hear it normally (only hear it when nothing is playing), then I wouldn't sweat it too much. All you can do is make sure that your wiring is clean and maybe try adjusting the LED settings and the "pre-amp" settings under the factory menu (maybe see if reducing the "System" setting under "Voice" helps reduce it). Once you try using things like ground-loop isolaters, etc, then there is a chance that the music fidelity is reduced even more.

Yeah have tried all the above and nothing changes.
The sound quality is poor also with higher ranges being really scratchy.
I am sure the unit would be fine if not using a higher end amp and just running the speakers off the head unit, I have read a few posts online and on youtube that the RCA output signal can be really poor with certain brands.
I just sent the unit back today for a full refund and will now be buying a brand name such as Alpine, Pioneer etc etc
i think it started recently
while i hear music especially when skip tracks (or sound stop&play) even in the menu of the phone is abit different in some apps
when i turn down the volume you hear it less "loud" (sound like blown speaker)
maybe software related? (i hope not hardware)
did it happen to anyone?
I just bought this dasaita screen after installing there is noise coming out from the speakers which is bearable but from my subwoofer its really worst.static noise is coming from subwoofer and if i play song and mute it noise increases and also in mute no song is playing the way i touch the screen noise moves on same way from my subwoofer.before i have the same system no noise was there.any fix??
