I’m trying to pull I2S off the Raspberry Pi. I have my own send board and external DAC. However, when I enable the “Generic” I2S Driver, I get “Nothing Selected” on the Playback Page, and there are no options in the dropdown. (Though there do seem to be 3 empty options). The Playback Indicator doesn’t advance, and of course, no audio.
If I set the Pi for “No I2S”, then there is an ALSA option. I have a USB input on my DAC as well, though it is not XMOS based. With No I2S Driver configured, and this setting on ALSA, the playback does advance, but still no audio.
I’m new to the Linux thing, and to be honest, have no idea how to troubleshoot from here. I did manage to get this information:
After enabling the “Generic I2S” Driver, and rebooting:
root@volumio:~# aplay -l
aplay: device_list:268: no soundcards found…
root@volumio:~# cat /proc/asound/cards
— no soundcards —
