pcm0:record:0: record interrupt timeout, channel dead (snd_t4dwave)

Hello all,

 I'm in the process of testing a softphone but it seems to be
a problem with the driver of the integrated soundcard for this

It uses the snd_t4dwave driver and each time I try to use the
software I get this error:
"pcm0:record:0: record interrupt timeout, channel dead".

It must be something in this driver because it works with
my home computer using the emu10k1 (SBLive) driver.

Is there some solution for this problem? 

How to reproduce it:

dd if=/dev/audio of=foo
pcm0:record:0: record interrupt timeout, channel dead
0+0 records in
