 |
|
Hi,
I've got a problem with my soundcard, a Audigy 2 ZS: Line-In does not work.
I tried playing around with the mixer, enabled Capture on channels, muted and unmuted channels and changed volume with no success. Sound playback works properly, as well as Mic-In, which is physically right next to Line-In on the card.
IIRC, Line-In was "Analog Mix" on my old Debian system, where it worked just fine. When I enable that channel on Gentoo and set its volume to max, I get an extremely small amplitude, which could be the result of interferences. It appears almost as if the phone jack was physically disconnected from the card (which it isn't, since it worked on Debian)
I'm using 2.6.22-gentoo-r8 with emu10k1 and ALSA compiled as modules (not alsa-driver)
/usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt yielded no useful information.
In my Google searches, I discovered that there are other people with completely different kernels or sound cards/modules who seem to suffer from the same problem, but none of them managed to get a solution...
I hope someone here has an idea.

There are emu10k1 mixer changes in 1.0.15 - try e.g. kamikaze-sources
Might be useful - "2005-02-19 True 5.1 surround" |

OK, in a last-ditch effort I just enabled, unmuted and maxxed every channel. It worked!
Result: in order for "Analog Mix" and "Analog Mix Capture" to work, you have to unmute "Line-In" under Playback. This does not make any sense, but it works now.
Thank you Paul for trying to help tho  |
