Hi I have a toshiba A100 (see attached file lspci-nnv) with a ATI SB450. Sound worked fine with kernel 2.6.17 and alsa 1.0.12rc1 (ubuntu edgy). I just did a fresh install of ubuntu feisty (kernel 2.6.20, alsa 1.0.14rc1) and the only mixer settings available are those of the modem, named off-hook and caller-id (see output of amixer, aplay -l , and the rest in attached file output_feisty)

I decided to upgrade alsa-driver and alsa-lib to 1.0.14rc2. after downloading the package, I unloaded all sound related modules (everything with "snd_" in it) in the right order and did: ./configure --with-oss=yes --with-cards=hda-intel;make; sudo make install; sudo modprobe snd_hda_intel A minor improvement: the mixer now shows controls for both the modem and the sound card (see output_after_upgrade_to_rc2), but unfortunately, there is still no sound coming out of those speakers (even though alsamixer shows control for PCM and the rest...).

Finally, I downloaded alsa-driver-1.0.14rc3 and gave it a shot. This time again, only modem related settings appeared in alsamixer, and no sound card stuff (see aplay and amixer in output_after_upgrade_to_rc3), and no sound either.

Does anyone know how to get some sound out of these speakers (given that it used to work with alsa1.0.12rc1...) ?

Thanks for your help Ben
