Yes.  As far as I can tell, at least.

I'm using the default daemon.conf shipped with Fedora 13, which contains
nothing but comments and newlines.  The sound card is: Intel Corporation 5
Series/3400 Series Chipset High Definition Audio (rev 06) in a Lenovo W510.
I've seen this problem on other machines (including in VMWare and VirtualBox
based VMs) too, but I don't know what sound hardware they were using.
