Hello,
A while back I had installed Ubuntu on a friend's laptop -a Sony Vaio VGN-FW21M- alongside windows Vista. Everything worked fine for a few years, until at some point last year linux went mute, while in windows both the analog and the digital outputs continued working. She couldn't remember doing something
"out
of the ordinary", but she was sure it was not after an update. Several
months
later, she upgraded to windows 7 but that didn't change anything. When I
got
my hands on the laptop, I checked for muted controls and other usual suspects, deprecated quirks (there were none) and all inputs and outputs of the
system.
HDMI audio works fine and so does the internal mic. Speakers, headphones
and
the external mic input do not work, even though pulse audio volume meter
acts
as if there were actually sounds being played. I followed all of Ubuntu's troubleshooting procedures, I removed and reinstalled alsa and pulse, I purged all configuration files, I created a new user and I even installed the
latest
alsa-packages from the "ALSA daily build snapshots" repository and nothing worked. I also tried booting into windows, setting all volume levels to the max and disabled power saving on all sound and multimedia devices. Next, I
tried
retasking the jacks one by one to no avail.
I remembered that I had performed the installation with an Ubuntu 11.10
live
CD, so I booted the computer off of that, but this time I got no sound. I tried with all the live CDs of a multitude of distros I had lying around, with kernels ranging from 2.6.35 to 3.16.6 and none of them worked, so I figured the
issue
must have something to do with windows. Is it possible that windows somehow started locking the audio chip on shutdown? If that is the case, can it be deduced from the logs and more importantly, can it be fixed?
I am attaching the output of alsa-info and lspci as well as kernel logs.
Thank you for your time. _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
I just noticed there might be a problem with the attached file after it got scrubbed. The file inside the .xz archive should get a .tar.xz extension so it may be opened. For anyone having trouble, I have uploaded the logs here: http://fwh4qw6313.1fichier.com/
Sorry for the trouble
