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.wavarecord: 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 *Device details:* *Type*: USB audio interface, 4 analog in, 4 analog out *Brand:* Vestax *Model*: VAI-40 *lsusb output:* ID 0a92:0091 EGO SYStems, Inc.
