At the moment I'm building a HTPC so I can record my favorite shows, watch dvd's, play music, ... . Everything is working out great but a couple of days ago I stumbled on a problem. I was happily watching a DVD while suddenly there was a pitch change in the sound (lower pitch), at first I didn't know wtf happened but suddenly it hit me that my PVR-software was also recording a show.
So I guess the following happened : WINdvd was playing the movie with the internal clock set to 48kHz when suddenly my pvrsoftware began recording a movie and must have thought is was a good idea to set the internal clock to 44,1kHz causing all the sounds coming from the soundcard to shift down in pitch.
Now I've got a couple of questions :
- What can be done to prevent this from happening? simple queston huh
- Why does my pvrsoftware actually need to use the soundcard as all it has to do is capture tv through a PVR150 (hardware mpeg encoder mind you) onto disk. I guess I'm a bit baffled as why it would route the sound through the soundcard for capturing when the captured data is not directly played.
- Could a solution be to activate (currently disabled in bios) my onboard, super deluxe craptacular, ac97 soundcard to record shows while using my terratec aureon space to play sounds? The idea is to let my pvrsoftware change the internal clock of the ac97 to whatever it wants while not touching the terratec's internal clock because it may be playing something.
