For reference relating to comment 12: 2.6.32.3-1mnb: First introduced the above 4 fixes. 2.6.32.3-2mnb: included 7b3a177 2.6.32.4-0.rc1.1mnb: included ed69c6a
Is there something more that needs done?
Thanks for feedback. Please, provide debug information:

Use 101 or 29 values for xrun_debug and try to put ksyslog messages to a relation with the audiable problems.
Just following up on this on behalf of a colleage.
He's set the 101 value and this annoyingly seems to fix his problem (well, no glitches to the ear anyway!).
However he does get the following messages:
kernel: PCM: hw_ptr skipping! [Q] (pos=1024, delta=8192, period=1024, jdelta=0/170/0, hw_ptr=140116992/140116992)
When he does the 29 value it spams the log >one every second and he didn't try too long to get it to fail before he switched to 101. I can get the full log of the above too if it's useful or run the 29 test and capture the output if it'll still help even tho it's not showing the error.
Another reply on the bug with some debug output:
