i read all of the posts here and commentated on one of them but comment was deleted as it was a question i guess, so i mage my own now, sorry for that...

Ok the problem:

USB sound card mic is not working, but when i edit the ~/.asoundrc to:

pcm.!default {
  type plug
  slave {
    pcm "hw:1,0"
  }
}

ctl.!default {
  type hw
  card 1
}

The mic and speakers start working, everything is great again!

and then i reboot and everything is back to:

pcm.!default {
  type hw
  card 1
}

ctl.!default {
  type hw
  card 1
}

and after that nothing works again (whell sound works but mic does not)

i have disabled BCM driver load in boot.conf and aplay -l and arecord -l returns only USB sound card.

so the big question of the century is how can i force the config file to stay the same as i have written? read only doesnt work it just throws error and stops loading UI, config in /etc/ also does not work. i have updated everything and upgraded also...

what now?

thanks!

  • All good, I just wanted to see what other answers were before duplicating an answer that doesn't work :p – Jaromanda X Sep 11 '18 at 12:47
  • Any ideas? It seems that the file is rewritten once the UI is loaded. bcs i added a script to crontab to execute after reboot and it does not work. also if i set .asoundrc to read only the UI wont load... – user1414449 Sep 12 '18 at 11:32

Ok, it is weird but for now at least works... i changed boot config file back to:

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

I had it turned off previously, and now it shows that it loaded bcm as a default device, but keeps the .asoundrc file alone and sends sound through the USB also the mic works...

Im confused, but yea...
