I bought a Pisound card in June 2020 and only had the time to try to use it now.
- I plugged the card to a RP 4 B 4GB I just received (pins are well connected),
- put both in a Pisound Case,
- flashed a micro sd with the last version of Patchbox OS
- plugged the whole to a power supply with amperages >=2.5
- ran wizard setup
- installed last updates
- reran wizard setup
When I do $ speaker-test -c2 -r48000 -Dhw:pisound
I have:
speaker-test 1.1.8
Playback device is hw:pisound
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Playback open error: -16,Device or resource busy
