I've seen this error message before after upgrading kernel # Ouch ... 
error while writing audio data: : Broken pipe

On the work machine do you have any digium hardware if so have you run 
rebuild_zaptel and genzaptelconf?

IIRC

WARNING[9036]: res_musiconhold.c:580 moh_register: Unable to open pseudo 
channel for timing...  Sound may be choppy.

with a 2.6 kernel you will get these errors as there is nothing to 
provide the relevant timing events.
