I have a Lenovo Y510 with a 4.1 audio system that took a bit of setting up to get working correctly on 10.10. I had to add:
Code:
options snd_hda_intel model=6stack-dell
to /etc/modprobe.d/alsa-base, which seemed to fix the issue. After upgrading to 11.04, the sound still works but the volume control and sound settings don't.
Okay so I know that there are hundreds of these similar posts concerning no sound and let me assure you...I've gone through most of them and at least 15 different methods of trying to obtain ANY sound.
I currently have Ubuntu 9.04 Jaunty dual installed with Vista on my Hp Pavilion Dv6 laptop. everything works great except for the no sound issue. This 'no sound issue' includes:
I recently built a new system using an ASUS P6T Deluxe V2 motherboard that has Intel HD Audio on-board. Sound from my computer worked just fine immediately after installing Fedora 12.
I just loaded 12.04.1 onto my Thinkpad T61 and I can't seem to figure out the issue with having no sound. My Master Volume is all the way up in the alsamixer and I've added the option "options snd-hda-intel model=thinkpad" line to my alsa-base.conf file (and rebooted) to no avail.
Hey guys,
I've read what feels like every forum post going with regards to this issue, nothing is helping, ive got no sound from my soundcard and yet Pulse volume metre for playback shows sound.
Just a follow up to this for anyone with the same issue. I ended up installing alsa, alsa-oss, and pulseaudio-alsa, and then configuring them with an Alsa Mixer (in this case xfce4-mixer, but there are others) and Pulseaudio Volume Control (pavucontrol). In Pulseaudio Volume Control, I disabled 'HD-Audio Generic', as it is for the HDMI output of my graphics card, and set 
I have tried killing pulseaudio. I have tried editing alsa-base.conf. I have tried alsamixer. I have tried uninstalling and reinstalling alsa-base and pulseaudio. I have tried everything I could find, but still no sound.
My computer is an HP Pavilion dv6 6190us with switchable AMD and Intel graphics. The sound stopped working suddenly after an update.
Laptop: Asus W7J
Audio device: ALC660

After so many many attempts to solve my audio problems when upgrading to Karmic, I finally found a working solution :p !
First, let me decribe what the problem was:
1) no audio card was detected at all
=> cat /proc/asound/cards returned an empty content
=> cat /proc/asound/devices did not include any audio devices
