Hi Janui,
thank you very much - all done as you suggested - and the Piano DAC 2.1 shows up as I2S device - but there´s no sound output at all
when not having activated the internal sound devices (HDMI & Jack)
If I activate them - sound output is ONLY on the left channel when Dual Mono mode is selected
Had to change the MPD.conf device to hw: 1:0 due to the other cards..
I also tried this but without success...
sudo su
rm /var/lib/alsa/asound.state
CARD="$(cat /proc/asound/cards | grep "\[PianoDACPlus" | awk -F " " '{print $1}')"
alsactl init $CARD >/dev/null 2>&1
amixer -q -c $CARD set 'Dual Mode' 'Dual-Mono'
amixer -q -c $CARD set 'Digital' 100%
amixer -q -c $CARD set 'Subwoofer' 100%
alsactl store $CARD
here my debug file:
