Hi Wise Ones,

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
