Sound Input NOT working [Latitude E6500] [snd-hda-intel]
So, I have a Dell Latitude E6500 laptop and I have installed Slackware 13.0:
Quote:
[rdagold@slack13 ~]$ uname -a
Linux mhq 2.6.29.6 #3 SMP Mon Dec 7 15:01:06 CST 2009 x86_64 Intel(R) Core(TM) 2 Duo CPU T9600@2.80GHz GenuineIntel GNU/Linux
Everything is just fine, except that I am completely unable to record audio, either using the built-in microphone or an external one. I can do this under Windows 7, which was installed in the laptop by Dell.
Audio output is ok, both for the built-in speakers and the external headset. I can listen to my mp3 in mpd/ncmpcpp and watch (HD) movies at youtube, for example.
However, as I have already mentioned, audio input is not ok. Following advice I found at Archlinux, Ubuntu and Suse forums, I have run alsaconf and I changed /etc/modprobe.d/sound:
Quote:
[rdagold@slack13 ~]$ cat /etc/modprobe.d/sound
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=dell-m4-1
I have then tried to record sound using sox (rec) and arecord applications. Both of them returned perfectly (and annoyingly) clean WAV files. I've also given Ekiga a try but it didn't work either, as expected.
Afterwards, I have tried several different alsamixer configurations for my capture devices and tried to record sound both via the builtin microphone and via an external one. It was all to no avail. Here are two screenshots of (rather obvious testing) configurations that I attempted:
Finally, maybe I should add that the currently installed alsa packages in the system are:
Quote:
[rdagold@slack13 ~]$ ls /var/log/packages/ | grep alsa
alsa-lib-1.0.18-x86_64-2
alsa-oss-1.0.17-x86_64-1
alsa-utils-1.0.18-x86_64-2
I hope to have included all relevant information. I feel quite lost on what to try next. Thank you all in advance for any help/suggestions/orientation you may be able to provide me!
I removed the (ancient) slackware alsa packages and I have just compiled (and installed) the latest stable version (1.0.22.1) of alsa-lib, alsa-utils and alsa-driver available at alsa-project.org.
Things look better now, although the problem remains. In fact, I am unable to change two of the values through amixer.
Current amixer output:

What I did with hda-analyser was open it in gui, unmute every pin, and set all volumes at half mast. Then I went intyo alsamixer and sorted things by ear. Try that.

Thanks.
There's some doo-dah on the page you see when you're logged in as the OP. On the left, IIRC, but it could be in thread tools. Or you can just edit the first post, go advanced, and edit the subject.
