I am running 11.10 on a HP/Compaq Presario sr1010z, and the video/audio was working fine with whatever was in the machine already. Then I installed a new video card (PCI/nVidia), which disabled the audio/video on the old one automatically. But that card didn't work out too well so I removed it.

Now the video is back to normal, but the audio is gone.

I have tried the following: 1. In BIOS, set audio to on/enable rather than Auto 2. Looked for hardware in System Settings > Sound, but nothing shows up there 3. But when I run the sysinfo utility, I get the description of the audio controller

When I do a 'sudo aplay -l', I get 'aplay: device_list:240: no soundcards found...' And then when I do a 'lspci -v | grep -A7 -i "audio"'

I get the following: 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS7012 AC'97 Sound Controller (rev a0) Subsystem: Hewlett-Packard Company Device 2a05 Flags: bus master, medium devsel, latency 32, IRQ 5 I/O ports at a000 [size=256] I/O ports at a400 [size=128] Capabilities:

00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.1 Controller (rev 0f) (prog-if 10 [OHCI])

Any ideas on how to fix this?

Thanks
