Hi, for the recording problem, please turn up the "Capture" volume control in alsamixer. For the missing input connectors, could you please add a PA log according to https://wiki.ubuntu.com/PulseAudio/Log ? Thanks!

[Yaroslav (slava-dr)]

Here it is. PA verbose log. But I don't know what more to do, it is already missing "input device".

[David Henningsson (diwic)]

Can you please open gnome-volume-control, go to the hardware tab, and make sure that in the "Profile" combobox, you have selected "analog stereo duplex". Does that resolve the problem with the missing inputs? If not, please attach a new PA log with this profile selected. Thanks!

[Yaroslav (slava-dr)]

After selecting "analog stereo duplex" in "Profile" combobox, now I can see on "Input" tab "Device sound for input" = "Internal Audio Analog Stereo". And chose a connector = "Internal Microphone". Checkbox "Mute" is unchecked. But I'm steel unable to record audio from internal microphone. (I've been trying making a test/Echo call to skype and it failed)

And after making PA verbose log(for the first time), I've got one more problem - I can hear sound only in my headphones. If I unplug them, I cannot hear a sound.

Here is Pulse Audio log for the second time with "analog stereo duplex" in "Profile" and trying to make test/echo call to Skype.

[David Henningsson (diwic)]

Hrm, your new pulseverbose log shows some "pool full" errors, which are unusual and tends to be caused by internal pulseaudio errors rather than hardware problems. Is the mic working in other applications than skype, e g does the input level move in gnome-volume-control?

[Yaroslav (slava-dr)]

In opened "gnome-volume-control" talking directly to an internal microphone hole, doesn't cause to move a input level meter.
And I yet doest have sound on internal notebook speakers.

[Yaroslav (slava-dr)]

HI! It's working for now!
What I've done - Open file in console by command:
sudo gedit /etc/modprobe.d/alsa-base.conf

and added to the end of file a line:
options snd-hda-intel model="lg"

Instruction finded here "http://help.ubuntu.ru/wiki/alsa"
May be problem was caused by updating from Ubuntu10.10 instead of clean install OS.
This string was persist in file(in Ubuntu 10.10- string was added manually) before update to Ubuntu 10.04 beta2, and after update OS - sound disappear. So I have been comment this line, reboot and nothing change, then I made this post. Today trying to help my self I uncomment this line, reboot and it help. It's seems to me everything is work.
How to close this bug report (should I do it?)

[David Henningsson (diwic)]

Well, first, the autoparser (the one used before you added model=lg) should have been working, so assuming that your conclusion is correct, we should improve the autoparser. However, given that there is a workaround and that I have a lot of other things to do at the moment I'm marking this as triaged for now. Thanks for reporting back!
