Port Replicator Audio not working

I have a Lenovo W520 on which I just installed openSUSE 11.4 (32-bit). Previous to this I had SLED 11 SP1 working fine (with regard to audio in and out of the port replicator) however, with the fresh installation of openSUSE 11.4 I am unable to get audio out of the headphone jack on the port replicator. Oddly enough the audio seems to be coming out of the headphone jack of the laptop itself but nothing out of the jack in the port replicator.

Below is the output of hwinfo --sound in case it helps:

Any suggestions would be very much appreciated.

I’ve never attempted to use a port replicator with GNU/Linux (as I don’t have such a device) so I can not offer any informed suggestions wrt that sort of hardware.

I do know in general in openSUSE-11.4 that installing the application pulse audio volume control ‘pavucontrol’ provides users more insight, and IMHO more control over the configuration of their PC’s hardware in GNU/Linux with pulse audio enabled. Whether that will extend to include the hardware of a port replicator, I do not know.

You could also check to see if the underlying alsa mixer controls have anything inappropriately muted. You can do that by simply typing:


amixer
