[alsa-devel] aplay: main:722: audio open error: No such file or directory

[Christopher Head]

Hello!
Apologies if this is not the right place to report this. I tried to use
the bug tracker at <https://bugtrack.alsa-project.org/alsa-bug>, but
both times I went to it (a couple of weeks ago and again today) it was
offline. Also, I am not subscribed to the list, so please include me in
replies (or tell me if this is not acceptable and I will subscribe).

I can't play audio on non-default devices.

Running aplay with no options, or with -D default, works fine. Running
aplay with -D hdmi does not work, failing with this message:

aplay: main:722: audio open error: No such file or directory

Running it in strace, I see that the last interesting thing it does
before printing that message is it tries to open /dev/snd/pcmC0D3p,
which does not exist; it should probably be addressing pcmC1D3p instead.

I have no ALSA configuration files anywhere.
