Re: Microphone does not work on wheezy laptop.
Good time of the day, Camaleón.
Thank You for Your time and answer.

That's what I get:

Any ideas? :o)

Oh, it's better:
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: STAC92xx Analog [STAC92xx Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
That gives us same
dell-m26
module from

I do! :o) I have told it is an old laptop that works very well still.

Thank You very much! - What did You check to find out that
"snd-hda-intel" should be specified here? - I understand that
"HDA-Intel" tells about this - but what about exact "snd-hda-intel"
cypher? :o)

I have done as You said:

# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1

install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5
install sound-slot-6 /sbin/modprobe snd-card-6
install sound-slot-7 /sbin/modprobe snd-card-7

options snd-hda-intel enable=1 index=0 model=dell-m26
Then rebooted, but w/o luck:

No, there was not.

I think the same. :o)

Hmm. I do not think the lap. is too old that the code will be removed
from kernel/ALSA to support the HW. You know at the time laptop was new
and latter - I thought, When will kernel support my mic. ? And You say
it is old. I think it is misconfiguration on ALSA/whatever side that
withheld mic. from working rather than a support issue.
If You will not get borried w/ the thread, I will supply any info
needed in order to solve the mic. problem.
Again. thank You!
Sthu.
