Confirming bug still present in Jaunty RC ** Description changed:
Recent Sony Vaios use snd_hda_intel for audio, which is generally good and supported by alsa >= 1.0.15, but the Ubuntu installer does not properly detect hardware and configure the driver. The well-known fix to this bug is to install the newest available alsa and add to the end of /etc/modprobe.d/alsa-base these 3 lines: alias snd-card-0 snd-hda-intel options snd-card-0 index=0 options snd-hda-intel model=vaio Then restart ALSA: ]$ sudo /etc/init.d/alsa-utils restart + + (In Jaunty, alsa-base has been renamed to alsa-base.conf and you have to + restart to effect any change) This enables the headphone jack, speaker muting on headphone insertion, the internal microphone (and I think the mic jack, though I haven't tested it), which otherwise don't work. Andy Whitcroft reckons this can be handled by the kernel's quirk subsystem if appropriate info is provided: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/195605/comments/24 So can people please add comments with their model number, the working "model=<something>" string from /etc/modprobe.d/alsa-base and attach the output of ]$ sudo lspci -vvnn | > lspci.txt For VGN-: NR11Z, N31M Use: options snd-hda-intel model=sony-assamd For VGN-: SZ650N, SZ61, FZ11S Use: options snd-hda-intel model=vaio For VGN-: FZ140E, FE41E Use: unknown ** Description changed: Recent Sony Vaios use snd_hda_intel for audio, which is generally good and supported by alsa >= 1.0.15, but the Ubuntu installer does not properly detect hardware and configure the driver.
