This is the output of amixer:

This is the output of sudo amixer scontrols -c 1:

Code:

 I set alredy "Audio.Mixer=PCM" or also to "Speaker" but nothing changed.

May the physic slider is the problem?
However I tried with an old soul card like that

https://www.ebay.it/i/232651613673?chn=ps&norover=1&mkevt=1&mkrid=724-128315-5854-1&mkcid=2&itemid=232651613673&targetid=883693966700&device=c&mktype=pla&googleloc=1008078&poi=&campaignid=9561703854&mkgroupid=98418255815&rlsatarget=pla-883693966700&abcId=1145978&merchantid=116448441&gclid=Cj0KCQjwmdzzBRC7ARIsANdqRRkkxlioPArQsfYx3vpvqxBfU9JtFg0RuRRy0zOSloeDDjiGc4dvUV8aAvswEALw_wcB

but it was the same.

If you need any other info, please tell me and I will post them as soon as I can.
Thanks

Please try to set MixerName=Speaker in /home/pi/.openauto/config/openauto_system.ini file.

Please modify /home/pi/.asoundrc file as below

Code:
pcm.!default {
        type plug
        slave.pcm "hw:1,1"
}

ctl.!default {
        type hw
        card 1
}

reboot the system and post the output of amixer -l command.

Did you revert the MixerName changes when connected the "3D Sound" sound card?

Thank you so much! It Worked!

The MixerName still set in "Speaker", and the amixer -l output is this:
Code:
pi@raspberrypi:~ $ amixer -l
amixer: invalid option -- 'l'
Invalid switch or option needs an argument.
Usage: amixer <options> [command]

Available options:
  -h,--help       this help
  -c,--card N     select the card
  -D,--device N   select the device, default 'default'
  -d,--debug      debug mode
  -n,--nocheck    do not perform range checking
  -v,--version    print version of this program
  -q,--quiet      be quiet
  -i,--inactive   show also inactive controls
  -a,--abstract L select abstraction level (none or basic)
  -s,--stdin      Read and execute commands from stdin sequentially
  -R,--raw-volume Use the raw value (default)
  -M,--mapped-volume Use the mapped volume

Available commands:
  scontrols       show all mixer simple controls
  scontents      show contents of all mixer simple controls (default command)
  sset sID P      set contents for one mixer simple control
  sget sID        get contents for one mixer simple control
  controls        show all controls for given card
  contents        show contents of all controls for given card
  cset cID P      set control contents for one control
  cget cID        get control contents for one control

However it seems to work well.

Now, should I leave the MixerName set in "Speaker" or change it to "PCM"?


(For the "3D Sound" sound card I tried both modes of the MixerName and didn't worked. Now it works too)

Thanks again

Great to hear that!

You do not have mixer named PCM. The only one is the Speaker. You can keep current MixerName value or just leave it empty (then it should be automatically detected by OpenAuto Pro).
