Hi Wise Ones,
I'm trying to set HDMI as the default output in asoundrc.
I have quite a few possibilities, listed here by aplay -L

By trial-and-error (how else to do it?) I find the following
commands generate audio output to a TV connected via HDMI.
aplay -D plughw:CARD=PCH,DEV=7 ~/music/tmh.wav
aplay -D hw:CARD=PCH,DEV=7 ~/music/tmh.wav
I would prefer a setting with dmix, but the following fails:
aplay -D dmix:CARD=PCH,DEV=7
Playing WAVE '/home/jroth/music/tmh.wav' : Signed 16 bit Little Endian, Rate 44100
Hz, Stereo
aplay: set_params:1343: Sample format non available
Available formats:
- S32_LE
Attempting to translate a working example to asoundrc, I find aplay (without -D option)
produces
sound output at the TV with the following:
pcm.!default {
type hw
card 0
device 7
}
However even after restarting firefox, it doesn't play to this
output.
I tried adding a ctl stanza:
ctl.!default {
type hw
card 0
device 7
}
This doesn't affect aplay, but firefox doesn't output to
headphones or HDMI with this setting in asoundrc.
I welcome any suggestions to get firefox to default to
the asoundrc setting.
TIA,
Joel

Hi Joel,
this is more informed guess work, so take it with a pinch of salt, but it
maybe worth the effort.
First try to create a plug device for your HDMI:
pcm.my_hdmi {
type plug
salve { plughw:CARD=PCH,DEV=3 }
}
Now create your !default with dmix:
pcm.!default {
type dmix
slave { my_hdmi }
}
Perhaps you can even shorten it to putting the
plughw:CARD=PCH,DEV=3
inside the default dmix device.
I know that getting all this to work with Firefox and GUI can be cumbersome.
Perhaps pulse might be in the way, but I know much less about Pulse than ALSA.
Still the plughw, which converts samplerates may help.
Best wishes,
Jeanette

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 know that getting all this to work with Firefox and

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

I do remember the ipc_key bit. I think it needs to go with the default
device. I think it's part of the dmix type. IIRC ipc_key can be an
arbitrary value, but must be unique for different dmix/dshare devices. I
hope this helps...
Best wishes,
