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

The default card has no "hdmi" device.
Try -D hdmi:CARD=NVidia (or better plug:hdmi:CARD=NVidia to get automatic sample format conversions).

Well, here’s what happens when I try either of those:
$ aplay -D hdmi:CARD=NVidia phone.wav Playing WAVE 'phone.wav' : Unsigned 8 bit, Rate 11025 Hz, Mono aplay: set_params:1233: Sample format non available Available formats: - S16_LE - S32_LE
(so, looks like it worked fine)

(no idea what happened here)
Actually, I was led to this problem initially due to trying to get Linphone to use my HDMI output for ringing but my normal audio output to headphones for talking. I discovered Linphone was using the wrong device node name, so I tried to narrow down the problem by getting Linphone out of the picture and just playing to different destinations with aplay.
What strikes me as weird is that sure, my default card doesn’t have an hdmi device—so why then is it trying to open a /dev/snd/pcm node whose name is a mixture of card and device that doesn’t exist? If it’s only willing to consider card 0 in this case, why is it looking up the name “hdmi” under card 1 and finding device number 3 at all, only to concatenate it with card number 0?
If this is considered not a bug, then I’ll be happy to leave you alone and poke the Linphone/Mediastreamer folks more instead.
