I followed the instructions at https://wiki.archlinux.org/index.php/Alsa but I still can't get the sound to work. I get a beep from the pc speaker from the line out and laptop speakers though. I had OSS working which was a bit noisy and I'd rather use alsa anyway. All the alsamixer channels are unmuted except for the external amplifier switch.

Can anyone help?

thanks
