I’ve got a Pi 5 with a DAC+ ADC. I’ve got Raspberry Pi OS installed on one SD card with the requisite entries in config.txt and the DAC+ ADC shows up as expected. I’ve tried the beta Patchbox OS but haven’t managed to get the Dac+ to show up at all (arecord -l and aplay -l both show no soundcard). I’ve duplicated the config.txt from the RasPi OS setup but with no success. I think I’ve followed everything in the Patchbox beta documentation and everything I have been able to glean from the forum.
Looking in the logs, I see
which presumably is an indication of the issue. Then I checked the sizes of the hifiberry-dacplusadc.dtbo files on the two installations and they were different. Copying the file from the RasPi OS install onto the Patchbox install got the card recognised, showing up in arecord -l and aplay -l. However, jack won’t start and I’m now seeing this:
Feb 01 13:34:46 patchbox kernel: pcm512x 1-004d: ASoC: error at snd_soc_dai_set_bclk_ratio on pcm512x-hifi: -22
Feb 01 13:34:46 patchbox kernel: HiFiBerry DAC+ADC: ASoC: error at snd_soc_link_hw_params on HiFiBerry DAC+ADC: -22
Can anyone give any suggestions?
