My sound has disappeared on my Ubuntu Lucid machine. It was there yesterday. I think we took a power cycle overnight and so my pc had rebooted this morning. After compiling PJSUA (the pjsip commandline sip client) and installing it, I tried to run it. No sound.
$ lsmod | grep snd
$ alsamixer No such file or directory,
Just because you need to know, I tried innstalling oss on this machine. Did n't get it working and TTHOUGHT i'd remove it. But some parts are still there.
I have googled for hours and have tried a dozen fixes. None have worked.
$ sudo lshw ....... *-multimedia UNCLAIMED description: Audio device product: 631xESB/632xESB High Definition Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 09 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:fcffc000-fcffffff ....... $ lspci ....... 00:1b.0 Audio device: Intel Corporation 631xESB/632xESB High Definition Audio Controller (rev 09) ....... $ sudo apt-get remove alsa-utils $ sudo apt-get install alsa-utils $ sudo apt-get remove alsa-base $ sudo apt-get install alsa-base $ sudo apt-get remove pulseaudio $ sudo add-apt-repository ppa:ubuntu-audio-dev/ppa $ sudo apt-get update $ sudo apt-get install linux-alsa-driver-modules-$(uname -r) $ sudo echo options snd-hda-intel model=generic >> /etc/modprobe.d/alsa-base.conf $ sudo echo snd-hda-intel >> /etc/modules
and probably others I've forgotten.
Root also does not see the soundcards. Of course this is Ubuntu so I can't just login from scratch as root.
I read a suggestion that I might have accidentally blacklisted the snd modules, but I'm not sure which blacklist that'd be in and how to un-blacklist them.
Any help? Anyone?
