I have a very strange issue with my sound recording in Fedora 14 x86_64. My microphone is picking up sound; when I use the GNOME Sound Recorder, I can see a change in the "Level" display. But, it only records one second for every ~5 seconds of input.

Basically, if I speak for 20 seconds, I'll get a 4 second file. When I play that file back, I hear my voice, but it's extremely choppy, as if it's only playing the first second of every 5 seconds of recording. I also use sound input in Skype, and people that I've audio called tell me that they hear the same thing - choppy sound as if it's only playing certain parts of input.

OUTPUT OF "lscpci -v", I'm only pasting the sound device.

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Subsystem: Hewlett-Packard Company Device 3656
Flags: bus master, slow devsel, latency 64, IRQ 16
Memory at f2300000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel

I know practically nothing about sound in Linux. All I've done is install pavucontrol and tweaked the input device and input volume, but of course, all that did was change the volume.

Any input/suggestions as to any process logs I should post would be greatly appreciated. - Xerebus

My solution (no idea if it was the RIGHT one) was to use the RT patched kernel. The Real Time kernel appears far more reliable for recording and playback of media.

Thanks, wpeckham, but is there another solution? I'd rather not install a patched kernel unless I have to.
