As you suggested, I lowered the latencies on several devices: 00:01.0 PCI bridge: Intel Corporation 82855PM Processor to AGP Controller (rev 21) Latency: 16 (was 128) 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] Latency: 20 (was 128) 02:03.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller (rev 01) Latency: 32 (was 168) 03:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP (rev 32) Latency: 64 (was 255) I set everything else to latency = 0, including ethernet, wireless, and firewire (which I don't currently use anyways). Unfortunately, this doesn't seem to have any effect on the symptoms. Does setpci perhaps require either a system reboot or a restart of alsa? (btw, is /etc/rc.d/init.d/alsasound missing in F7? I saw a few threads on this for FC6, but there didn't seem to be a resolution). In any event, are these new values more reasonable for a laptop? I did find a few informative links on this issue, and it sounds like many people swear by tweaking those latency values (http://www.sabi.co.uk/Notes/linuxSoundLatency.html, which also includes links to other pci latency pages, if anyone is interested). Anyways, I will try disabling devices one-by-one this weekend, and if that doesn't help, I'll probably try building an older kernel.
