Hi Alsa users,
I previously asked this question on Linux Audio Users list.
Since no one could help, I'm posting here.
I'm able to play sound with this command:
aplay tmh.wav -D plughw:CARD=PCH,DEV=7
I would like to make this the default device in asoundrc.
I tried this asoundrc:
pcm.hdmi_out {
type plug
ipc_key 5641
slave {plughw:CARD=PCH,DEV=7 }
}
pcm.!default {
type dmix
slave { pcm "hdmi_out" }
}
Then trying 'aplay tmh.wav' results an error:
ALSA lib pcm_direct.c:2079:(snd1_pcm_direct_parse_open_conf) Unique IPC key is not defined
aplay: main:830: audio open error: Invalid argument
I'll appreciate any suggestions.
For reference aplay -L lists the following devices.
