I had a similar problem with my PVR 250 with the 0.2.0 series ivtv drivers.
The fix in my case was to pass along options to the msp3400 module.
in /etc/modules.d/aliases :
options msp3400 once=1 simple=1 standard=0x20
followed by the obligatory modules-update ; depmod -ae
This is the one that worked for me. Note that standard=0x20 is for NTSC in
the US. PAL/SECAM needs standard=0x09 according to this link (read the Q:
about tinny audio).
