ALSA, How to turn capture volume bar on?

kaz2100 · 09-06-2008, 09:01 PM

Hya,

Problem is, microphone is not working.

Hardware is
Debian etch, on Toshiba laptop Satellite. Card is Intel 82801CA-ICH3 Chip is Yamaha YM753.

Software is Skype
Speakers are working, but not microphone.

Several threads suggest to adjust "Capture volume" using alsamixer. However, it is turned off and I do not know how to make it active. I think I have all necessary kernel modules compiled and loaded (lsmod output follows.) One point I am not sure is snd-ymfpci module. Documents in kernel source says it is for YMF75x, while config option page days Yamaha YMF724/740/744/754 (NO 753!!).

Does anybody know?

Happy Penguins!

The last one is a kind of discouraging.

using alsamixer use your arrow keys to go to mic and press the m key. It will change from MM to OO then use the up and down arrow keys to adjust the volume. Just tested and this is what I used to turn the mic on and off on my etch system.

Hya,

Thanks for your reply. Yes, M (or m) works for many other controls, but not for capture. Space bar looks to select, however, microphone does not work....

Happy Penguins!

You can press tab to see the capture sliders within alsamixer.

Hya,

Thank you for your reply. Yes, however, tab key works to change Playback -> Capture -> All -> .... (functionally, same as Func keys).

For some reason, I reinstalled libasound2 package using aptitude, which solved partially my problem. A little bit more to go. I will post as soon as I sort things out.

Happy Penguins!
