Hi all,
I'm hoping for some ideas to get a maya44-based audio device working in ALSA on a Ubuntu 20.04LTS x86-64 audio workstation.
The device shows up in 'arecord -l' and 'aplay -l'. But when I try to record from it with arecord, I get:
arecord -D hw:5 -t wav -c 2 -f S16_LE -r 44100 /tmp/foo.wav
arecord: main:831: audio open error: Device or resource busy
arecord: main:831: audio open error: Device or resource busy
The device shows up in alsamixer, with 2 x stereo line outputs, but only 1 x stereo line input.
My kernel does have the 'maya44' code compiled in.
Further system and device details below.
Can anyone please help me get this working?
Cheers
Daid
