Sound stopped working

Hello,

I have an issue with sound (input and output), generally it isn't working but it was working perfectly. I have never changed anything in config, default was just perfect for me.
It all started when I installed pulseaudio to get sound in Skype, after first reboot sound worked perfectly even in Skype on default settings, after next reboot the sound has disappeared.

I'm running Arch Linux x86_64.

$ lsmod |grep '^snd' | column -t
snd_pcm_oss            49005   0
snd_mixer_oss          21998   1   snd_pcm_oss

$ aplay -l

Re: Sound stopped working

Maybe it is just muted? What if you run alsamixer? Try selecting the correct sounding card while on it (F6 key).

Re: Sound stopped working

It is the default behavior of alsa. It is documented on the Wiki.
