Description:
Alsamixer shows only one channel called PCM. It's unmuted, and the volume

Same hardware and same issue reported for Sony VAIO FE series and SZ
series.

Try the patch below. It's to ALSA CVS version.
If nothing is changed, pass "model=vaio" module option.
Would be nice if you can test the recording, too.

now sound output works, also with headphones,great work. Here is the
alsamixer status:
Playback : Master , PCM
Capture: PCM (disabled) , CD , Mic (disabled) , Capture , HP ("L R CAPTUR"
written in red on top of disabled control) , Unknown (disabled)
Mic volume Control is disabled, so I can't test capture.

Push space on 'Mic' in capture view to select as the source. I'm not sure
whether it's a mic jack or whether any internal mic is equipped on this
laptop.
It's better to show the content of /etc/asound.state after running
"alsactl store", though.
----------------------------------------------------------------------
sk0rp10 - 03-14-06 16:47
----------------------------------------------------------------------
On this Laptop there is an input jack for external mic and also an
integrated microphone.
Another issue : /dev/dsp and /dev/sound/ are missing , so apps like flash
player don't work

/dev/dsp is irrelevant. You didn't load the necessary modules.
Apparently, the capture switch is off, and "HP" is chosen as the recording
source. Change it via alsamixer.
----------------------------------------------------------------------
rlrevell - 03-14-06 17:06
----------------------------------------------------------------------
On my Ubuntu system the flash issue can be fixed by setting
FIREFOX_DSP="aoss" in /etc/firefox/firefoxrc.
You can also load the snd-pcm-oss module but this is not as good as any
app using /dev/dsp will block your soundcard

tested on the vaio sz110. Sound output and recording works perfectly now.
Thanks a lot!
