Internal microphone on NV53 not working

[Noel J. Bergman]

Binary package hint: pulseaudio

Gateway NV5302u. Audio plays, but nothing appears to work for recording. Not the little recording applet, not Skype. Others have reported the same problem around the Internet, e.ghttp://ubuntuforums.org/showthread.php?t=1361263.

I've gone through http://ubuntuforums.org/showthread.php?t=789578, such as it works with Lucid, but to no avail.

Daniel, attached is the output from alsa-info.txt. On IRC, you asked if I could post output from hda-verb. Can you reply back with the command you'd like me to run? I've got hda-verb installed, but haven't used it before. I have access to the laptop until this afternoon, and then again not until the end of May.

[Daniel T Chen (crimsun)]

I don't want output from hda-verb. You should *use* hda-verb to set a VREF (see the Intel Azalia/HDA specification) on node 0x1d (your int mic).

I am also experiencing this bug on a Gateway NV53 series under Ubuntu 9.10 and 10.04.

Hi Daniel,

can u tell me which verb to set (if possible a hda-verb command) so I can try it?
I have installed both hda-verb and hda-emu, so if you need something let me know

[nikolayds (nikolayds)]

Here is hda-emu output for hwC1D0

This bug seems to be plague all hda SBx00 microphones
I saw a bug 480815 and the user gilianphilippo had a working solution. I have tweak it a little and tested it works on NV53

Add following
options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes
to /etc/modprobe.d/alsa-base.conf

Restart and problem is fix. I am looking forward to have it workout in the upcoming releases of Ubuntu.

[Daniel T Chen (crimsun)]

Noel J. Bergman, do you still need assistance with this bug report? I apologize for not following up promptly, but $life has been quite hectic. If you still need assistance, please first also reproduce this symptom using the latest stable mainline build at http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/

nikolayds, please file a separate bug against alsa-driver using ubuntu-bug so that we can collect all your necessary hardware information. Also, please clarify which fix you needed. Did you need *only* position_fix=1, or did you need *both* position_fix=1 and model=laptop?

[nikolayds (nikolayds)]

I needed both lines/I added both lines, did not test only with one of them. Will do that tonight and file a bug with lucid. I have the same hardware, as above, Gateway NV53 laptop.

[rwmarch (rwmarch)]

I added the lines:
options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes
to /etc/modprobe.d/alsa-base.conf
on my NV53 running Lucid.
Doing so restored the internal microphone to normal. Fixed in Skype as well.

[Daniel T Chen (crimsun)]

Please make sure that your codec information and lspci -nv information
ends up attached somehow to this bug.

This fix is not working in Natty 64 Bit

[drklunk (wlong21)]

my issue is not with the microphone but with the output through headphones. when I plug my headphones into my laptop (NV530-) audio still plays though the speakers. attached is my alsa-info.txt
