I have the same error message but on playback. Device is SiS 7018.

Note the last line of error message is only after playback for about 3
seconds. The first 3 seconds playback fine though, with any software
(tried mpg321 and xine -A oss).
Since the patch you offered no longer can apply, I did the minimum
change on t4dwave.c and compiled a new kernel, tried, without luck (same
error mssage). What I did is:
@@ -725,7 +726,7 @@
intsrc = tr_rd(tr, TR_REG_MISCINT, 4);
if (intsrc & TR_INT_ADDR) {
chnum = 0;
- while (chnum < 64) {
+ while (chnum < 32) {
mask = 0x00000001;
active = tr_rd(tr, (chnum < 32)? TR_REG_ADDRINTA : TR_REG_ADDRINTB, 4);
bufhalf = tr_rd(tr, (chnum < 32)? TR
Looking at the source code the problem triggered by "while (chnum < 64)"
should have been fixed already, thus this bug should be closed, mine is
probably a different one.
Anything to try for me?
