If you have an analog signal (e.g., regular cable), how would you
deliver the audio to the sound card? If you have digital cable you
could run a cable from the set top box audio-out to the sound card.
Or are you saying that by running a patch cable from the tuner card to
the sound card you'd bypass the tuner card's DSP and send the signal
straight to the sound card, where it is then digitized?
Sorry if this is a stupid question. The topic interests me because I'm
getting some strange modulation (think wah-wah effect) and soft pops in
my audio, sorta like someone knocking softly on the wall. It's
annoying. I have two PVR-250's on an ASUS P4P800 mobo with an M-audio
Audiophile 2496 sound card. I get really excellent audio with mythmusic
and mythvideo, but the audio from live tv or recorded shows has these
Could it be because I'm getting sound across the PCI bus?
