After an update to Unbuntu 12.04, the sound is now off. With Rhythmbox, I can barely hear the songs playing with the headphones connected, but nothing with the internal speakers.
I have a Sony Vaio PCG-7V2l with the following sound card hardware:
$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 $ cat /proc/asound/card0/codec* | grep Codec Codec: SigmaTel STAC9872AK Codec: Conexant ID 2bfa
The first thing I tried was to run alsamixer and the sound settings for volume control or mute being set. Everything looks normal and nothing muted. I then updated the sound drivers on 03/03/2013 and rebooted:
sudo add-apt-repository ppa:ubuntu-audio-dev sudo apt-get update sudo apt-get dist-upgrade
'options snd-hda-intel index=0 model=vaio"
to the end of
I also tried adding
model=auto and model=generic to
And I also tried killing pulseadio. with:
sudo killall pulseaudio; rm -r ~/.pulse*
Does anyone have any solutions to this problem?
