Errors in 2.4.18 cs46xx driver

While playing the game Doom Legacy (v1.32beta4), the sound suddenly quit on me. After exiting the game I found these entries in my system log:

Apr  6 22:54:58 mercury kernel: cs46xx: powerdown DAC failed
Apr  6 22:54:58 mercury kernel: cs46xx: cs_release_mixdev() powerdown DAC 

failure (0x1)

My kernel:
Linux version 2.4.18 ([email protected]) (gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)) #1 SMP Mon Feb 25 19:45:39 EST 2002

This is with a Turtle Beach Santa Cruz sound card. The card is apparently not sharing an IRQ with any other devices.

Is this a problem that can somehow be worked around by a lowly end user?

Thanks.
