My XPS M1330 uses the same chipset and has the same problem. I have all mic levels raised to maximum but the internal mic barely registers any input. It's too quiet to be usable.

In previous releases of Ubuntu there was a mic boost option in the ALSA mixer, but there isn't anymore.

Of course, it works in Windows...

[poelcat (poelcat)]

I have the same problem... same hardware... same release. Is there a manual work around?

[Raymond (superquad-vortex2)]

there are 40dB gain, are you sure that the left and right channels are out of phase

try muting one channel

use audacity to capture stereo from hw:0,0 to check the phase of the channels

Simple mixer control 'Mux',0
  Capabilities: cvolume penum
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 4
  Front Left: Capture 4 [100%] [40.00dB]
  Front Right: Capture 4 [100%] [40.00dB]
Simple mixer control 'Mux',1
  Capabilities: cvolume penum
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 4
  Front Left: Capture 4 [100%] [40.00dB]
  Front Right: Capture 4 [100%] [40.00dB]
Simple mixer control 'Mux',2
  Capabilities: cvolume penum
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 4
  Front Left: Capture 4 [100%] [40.00dB]
  Front Right: Capture 4 [100%] [40.00dB]

[Denis (denis-dellsale)]

Channels are cophase.
The gain value is 100db.
Distance to mic is about 30-40cm.

Dell XPS M1530
Ubuntu 12.04.2 fresh install
Low mic volume
STAC9228

This problem was fixed in the 2.6 kernel used in 8.04 and 10.04. Dell had recommended installing the backport kernel modules and that fixed the problem in 8.04. Ubuntu 10.04 had the fix in place and no backported modules were necessary. Now, the 3.5 kernel doesn't include the same volume boost fix.

Have tried dell-3stack, dell-bios, and auto on snd-hda-intel module.

[Raymond (superquad-vortex2)]

try hda-jack-retask to remove one of the internal mic 0xc (analog) and internal mic 0x13 (digital)

[Henning Bostelmann (hb540)]

Same problem here on:
Dell XPS M1330
Ubuntu 12.04
Kernel 3.2.0-54-generic-pae #82-Ubuntu SMP

[Henning Bostelmann (hb540)]

Re hda-jack-retask: It doesn't show any internal mic 0xc for me, just internal mic 0x13 .

[Raymond (superquad-vortex2)]

you have to open new report if your notebook does not have same hda codec , same init_pin_config, same number of speakers , jacks and mics
