| I meant to share this last night but sidetracked. These are the specs from the DAC packaging, fwiw. Does this help to address format/capabilities questions?

Generally for trouble shooting I would hit the card directly:
alsaplayer -i hw:1,0 filename.flac
aplay --device=hw:1,0 filename.flac
aplay can't handle anything but straight PCM formats. in addition, using
hw:XXX means that the requested data format MUST match the hardware
capabilities. if you ask for a sample rate or channel count not supported
by the hardware, the device configuration will fail. this is why the
"default" device with ALSA is never hw:XXX but at minimum plughw:XXX (which
can do just about any format conversion necessary). |
