I think this lockup is caused by some kind of design flaw in the ISDN
card (or a driver bug). Few other users have reported similar problems
when using some ISDN adapter (I recall it was made by Hayes) while playing
sound. There are no problems as long as the ISDN adapter is not used at
the same time with sound.

Best regards,
