I am using arch linux and i was using pulseaudio suddenly today pulseaudio stopped working and no sound is coming in both my speaker and headphone. I can see pulseaudio is running properly and I am able to hear the beep sound from my computer but not any other sound??? any suggestions please I had already read the wiki page. I run pulseaudio as root and I had added my root in audio group
Just kill the
pulseaudio process, and re-launch it would be fine:
killall -9 pulseaudio; pulseaudio
For that reason I no longer uses pulseaudio on my system, I fallback to alsa now.
P.S some app can specify which sound output to use, e.g mplayer, what application that doens't produce sound that you're using?
First, let me recommend installing pavumeter, which lets you see the in/out levels that pulse thinks are happening.
My guess is that something came unstuck in your ALSA configuration. I'm not really sure what Pulse's view of audio architecture is, but I find that I normally have to twiddle settings with 'alsamixer' to make a linux desktop's audio work right. (For instance, mic being mixed into output, or the wrong inputs or outputs, etc). Make sure you look at all the "soundcards" alsamixer shows, and both the rx and tx channels.
I guess it would also be useful to know what you mean by being able to hear the beep. Do you mean from the motherboard speaker?
