	Have a 1.6.1_STABLE i386 box playing mp3 and ogg files using
	mserv. All works fine, except sometimes when printing (either
	via lpt or ulpt) the audio becomes garbled - frequently sounding
	as if the singer were gargling.

	ulpt seems more prone to cause this than lpt, but both seem to
	be guilty.

	Skipping to the next track usually clears the issue (for a while).

	Does anyone have any thoughts as to whay might be casuign this?
	I say something similar a while back on a different eap while using
	a speedtouch USB ADSL modem. Could it be an issue specific to the
	eap driver? If somone could recommend a reasonable cheap pci audio
	card I'd be happy to confirm that :)
