Hi !
I have a DELL XPS and I can't hear anything in my microphone.
lspci output:
| Code: | neobalam neoriddle # lspci

Hmm, this looks suspicious:
[quote]Simple mixer control 'Capture',0
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 14
Front Left: Capture 6 [43%] [9.00dB] [off]
Front Right: Capture 6 [43%] [9.00dB] [off] [/quote]
If you want to capture something, maybe it shouldn't be [off]?
Additionally have a look at 'Input Source' and see if you can change it to say something like "microphone" or so.
You can also try to play with 'Mux', as it's set to 0 and it might need to be changed. |

| Use alsamixer. It's explained in the Gentoo Linux ALSA Guide in chapter "Volume Check!". Alternatively, see "man alsamixer". Just for testing you can increase the volume of everything to the maximum and of course unmute everything. |

I tested the sound like "Gentoo Linux ALSA Guide" explains, but it does not work yet.
here you have more info about my sound card:
| Code: | neobalam neoriddle # cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xefebc000 irq 20
neobalam neoriddle # cat /proc/asound/version

neobalam neoriddle # cat /proc/asound/oss/sndstat

Kernel: Linux neobalam 2.6.21-gentoo-r4 #6 SMP Thu Jul 26 12:52:12 CDT 2007 i686

and there is another rare thing, when i try with alsaconf, it does not find any PCI sound card.
and volume levels are correct, let's see:

| The "Input So", which selects which input source should be used, is set to "Front Li". Can you try to change it and see if you can choose something else, e.g. "Mic"? |

As a root run:
in order to regenerate whatis database. Next run:
You will see the list of command line tools interacting with ALSA. Read the man pages of the interesting ones. E.g.:

| It all seems quite OK. I'm sorry, I cannot help you further, because I don't own Dell XPS. A quick googling for "dell xps internal microphone" reveals that people have a lot of problems with it. I suppose that's a hardware problem of some sort. |
