Comment (by mrussotto at speakeasy.net):

 I believe the stuttering may be related to the original bug, but not
 directly.  It happens because during the switch from digital to analog,
 too many sound interrupts occur and the driver disables the sound
 interrupt to save the system.  I have a workaround for that -- add

         cx_set(MO_PCI_INTMSK,0x02);

 to snd_cx88_pointer() (in cx88_alsa.c) just before the return statement.
 This simply turns the interrupt back on every time sound data is
 requested.

 I think there must be some sort of race occurring during the switch from
 digital to analog that results in this and in the loss of analog sound.
