@luz I've repeat all the mentioned steps and it works now... I can't belive

My fault was that I wasn't applying 210-omega2-sound-max98357a.diff correctly. The patch fails for 0.3.2 b238, and I wasn't applying it correctly (doing changes manually)

I've tested using mpg123 mp3 player and aplay commands. Works fine.

Also thank you for the tip about mixer and hxcmodplayer

Dear community
I'm using Omega2S as black box for music playback using I2S, and have noticed that music is interrumped every time I run a write to flash command (just few samples, very easy to check using a wave 1KHz tone).

In order to check it I run madplay, or aplay, or mpd player with a 1KHz tone (mp3 or wave format do the work) and simultaneously write to flash using a command like echo "some_text" > /test_file (/test_file is located in root of squash file system).
I've check the log files and dmesg, but no warning/error/underrun is shown.

It will be nice if someone can help me to debug further such issue.

Best regards,
Sergio

max98357A

Hi @luz I was trying to make max98357A work and have find your post and patches but it doens't work, please let me now your thoughts about the process I've followed..

Basically I've downloaded a clean onion distro and download 210-omega2-sound-max98357a.diff. After configure onion-minimal-build.sh I've apply your patch. "make" works but alsa shows now audio cards.

I'm afraid that I've to insert max98357A module after board boots.. but not sure. It would be nice to know your opinion.
