Raspberry 5 pi + HifiBerry Dac8 configuration

[jplesset]

I am attempting to upgrade an old Pi3 with MPD outputting to a "7.1 sound card" with a Pi 5 and a HifiBerry DAC 8+ hat. So far, I have been able to make sound, but not really get the hat configured so I can set up my file streamer or anything further.

when I try to address any of the 8 outputs (HifiBerry says these are not stereo pairs, but individual channels), I just get errors like:
jay@raspberrypi:~ $ aplay -D sndrpihifiberry,DEV=0 --dump-hw-params /dev/zero
ALSA lib pcm.c:2666🙁snd_pcm_open_noupdate) Unknown PCM sndrpihifiberry,DEV=0
aplay: main:831: audio open error: No such file or directory


I know I'm being stupid, but I've been stuck here for months. . .

Thanks for any advice!

I wish i could help. I really love the idea of the dac8x pi5 combo. Super affordale with a ton of dsp potential. Out of curiosity, Have you tried the dac8x with moode?

Since I've not been able to address any of the 8 channels individually yet, no........

Thanks, though.

jay@raspberrypi:~ $ aplay -D sndrpihifiberry,DEV=0 --dump-hw-params /dev/zero
ALSA lib pcm.c:2666snd_pcm_open_noupdate) Unknown PCM sndrpihifiberry,DEV=0

That's correct - there is no PCM device like that. The name should be e.g. hw:sndrpihifiberry,DEV=0, or as hinted in your aplay -L output: hw:CARD=sndrpihifiberry,DEV=0.

Offtopic: I would recommend to use the [CODE] tag for the listings so that indentation is preserved and the message is readable. Thanks.

Thank you! That does help:
