I made a small mistake in my previous comment. It's SiS SI7012, not S17012.
Here's the possibly related bugs I mentioned: - Bug #47221 SiS 7012 doesn't work - Bug #26376 SiS 7012 chip Breezy: Sound works fine but volume can only be set to mute or 100% - Bug #26637 SiS driver performance regression with linux-image-2.6.15-7-686 - Bug #52319 Sound Card on Haier H51 laptop is recognised, but not functional. I left a comment on each one to try the workaround described here. -- On-board SIS sound card needs muted "IEC958" https://launchpad.net/bugs/19648 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
