Same problem here (amd64). Audio device is "nVidia Corporation MCP51 High Definition Audio (rev a2)" according to lspci -v.
Once solved the problem by compiling the alsa kernel module from the alsa source package, but this kernel module has been overwritten by the latest kernel updates. As this seems to be somewhat independent of the hardware and affects important functionality, I also vote for heightening the priority. -- alsamixer broken in hardy - intel hda https://bugs.launchpad.net/bugs/192382 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
