 |
|
Well, my sound was working fine with a new install of Gentoo. I installed Firefox which drew in Pulse Audio and now my sound card won't work normally. Everything I have searched says I need to set my sound card as default, but it already is:
| Code: | ~ $ cat /proc/asound/cards
0 [CMI8738 ]: CMI8738-MC6 - C-Media CMI8738
C-Media CMI8738 (model 55) at 0x9c00, irq 16
1 [Lite ]: USB-Audio - Rocketfish HD Webcam Lite
Rocketfish Rocketfish HD Webcam Lite at usb-0000:00:0b.1-1.7, high speed
2 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfcffc000 irq 16
~ $ aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

If I use "speaker-test -t wav -c 2 -D front", I DO get test audio. How do I fix this?

Being helpful there...  even less so than I tend to be.
@rkfsm: what's the output of 'aplay -v /dev/urandom' and 'paplay -v --raw /dev/urandom' ? |

I have removed Pulse Audio just to see and it did not fix the issue. Here is the output you asked for. There was no sound from the speakers during this.
| Code: | ~ $ aplay -v /dev/urandom

Well, not sure about aplay, as due to thrashing around, the list of devices might have changed, but as for paplay, 'Connected to device alsa_output.pci-0000_01_00.1.hdmi-stereo' is your problem - it's picking up HDMI as the default output.
'pactl list sinks' will give you the list, 'pactl set-default-sink <foo>' sets it - IIRC it should be preserved across reboots/logouts.
Same for sources. |

This might solve a problem I've had with pulseaudio for some time
I'll give it a try next time I do larger system maintenance changes
Thanks !
