because It seems to not be able to using alsa-lib's sound-test in webapp shell , I used docker ubuntu container with --device /dev/snd option, so I could get a sound card name "anx7625"
but when i did a speakertest, I seems did not work . speaker did not make any sound.
is the soudcard name "anx7625" correct?
what is the correct sound card name of portentaX8 and max carrier's linux system?
@dorei, your topic has been moved to the dedicated Portenta section of the forum.
I'v checked a boot log using dmesg , I found some logs about sound card
[ 2.902897] ALSA device list:
[ 2.905892] No soundcards found.
...
[ 6.852935] cs42l52 2-004a: Failed to apply regmap patch: -6
[ 6.887479] cs42l52 2-004a: CS42L52 Device ID (20). Expected E0
I think the anx7625 is not a sound device of portenta max carrier,
and I want to know why the log said failed to apply regmap patch:-6
