Description of problem: Since upgrading from FC3 to FC4, sound will not capture in stereo from line input. Attempting to capture in stereo results in only the left channel. I tried this on another machine upgraded earlier, with a different sound card, and got the same results. Booting back into FC3, stereo capture works; boot FC4, only get one channel. Same results using arecord or audacity. Seems like it might be a seetting someplace, but I can't find it. I don't have any other sound inputs wired up, so I don't know if any other inputs have the same problem. Version-Release number of selected component (if applicable): machine 1: kernel 2.6.14-1.1653_FC4smp Xalsa-lib-1.0.10-2.FC4 alsa-utils-1.0.10-1.FC4 alsa-lib-devel-1.0.10-2.FC4 machine 2: 2.6.14-1.1644_FC4 alsa-utils-1.0.9rf-2.FC4 alsa-lib-1.0.10-2.FC4 How reproducible: always. Steps to Reproduce: 1. Upgrade from FC3 to FC4 2. Attempt to capture stereo sound with arecord or audacity Actual results: Sound is captured in mono on the left channel, or only the left channel is captured (I can't tell for sure) Expected results: Both left and right channels are captured.

Some how-to for the latest alsa-driver and FC4 is here: http://people.redhat.com/stransky/alsa/ Could you check it?
I tried the latest stable release on machine #2. Same problem. I'll try the development version next on that machine.
Ah! Success! Using the 1.0.11rc2 I kits can now capture both channels on machine #2. I'll work on updating machine #1 over the next few days (it's my main machine and I gotta have my backups), but I fully expect this will resolve the issue. Thanks! (plus I learned some new stuff about rpmbuild in the bargain :)).
I have the same problem from one month ago, using a Fedora Core 4 after having updated it. I can't capture stereo from line-in using my motherboard integrated soundchip or using a SBLive 5.1 (with integrated soundcard disabled). kernel-2.6.15-1.1833_FC4 alsa-utils-1.0.10-1.FC4 alsa-lib-1.0.10-3.FC4 alsa-tools-1.0.9-1.fc4 alsa-utils-debuginfo-1.0.10-1.FC4 /proc/asound/cards 0 [Live ]: EMU10K1 - SB Live [Unknown] SB Live [Unknown] (rev.10, serial:0x80661102) at 0x2440, irq 12
