I have searched the board for this issue and found this topic:

but I am still at a loss.
My GB-PVR setup can record video and sound, but on one channel (FOX) the audio on recordings sounds like it's clipping when played back in GB-PVR, evidenced by pops when the audio gets particularly loud. It doesn't do this on any other channel that I've noticed, it doesn't do it in LiveTV mode on this channel, and it doesn't do this when I play the same file back in WMP. Only a show recorded from FOX played back in GB-PVR seems to have pops/crackles.
I have tried altering the settings in my mixer (the sound device is a built-in C-media chipset on an NF2 mobo), including changing the master volume level and wave output level. What settings here have other people used? As low as 50% I still get pops. I have tried searching on google for crackling problems with C-media devices, but didn't come up anything relevant.
I have tried settings in ffdshow's audio decoder configuration, lowering the master output volume and trying normalization. I have also tried setting different audio renderers in the GB-PVR config program, to no avail. No programs are running in the background other than the Hauppauge IR utility.
Any help would be greatly appreciated.
System:
XP 2400+, 256MB RAM, NF2 motherboard with built-in C-media AC97 Audio
GeforceFX 5200
Hauppauge WinTV-PVR 250
