I had to add some "stuff" to the module configuration to get sound from my card, which is: pyrope ~ $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Headset [Logitech USB Headset], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Intel [HDA Intel], device 0: ALC885 Analog [ALC885 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Intel [HDA Intel], device 1: ALC885 Digital [ALC885 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 It was the ALC885 that was troublesome to get going. Have a look in /usr/src/linux/Documentation/sound/alsa/ at the HD*.txt for information. Good luck, Roger
