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?
for my dayjob , i use a computer which is dualboot with windows and ubuntu , which is almost always having linux-next. and audio works for both my os.
I am attaching the output of alsa-info and lspci as well as kernel logs.
i think you forgot to attach the files.
thanks sudip
