To review, the following plays through TV speakers:
aplay tmh.wav -D plughw:CARD=PCH,DEV=7
With the .asoundrc below,
aplay tmh.wav
results in:
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 get this same error even after specifying ipc_key in .asoundrc:
pcm.hdmi_out {
type plug
ipc_key 5641 # inserting this line, and using various values doesn't help
slave { plughw:CARD=PCH,DEV=7 }
}
pcm.!default {
type dmix
slave { pcm "hdmi_out" }
}

I believe firefox will honor the !default setting.
Thank you,
Joel
