Ok i have a problem with my PCTv-PRO ! when my CPU work or my HD read i ear in my speaker a very strange sound! LISTEN: (USE RIGHT BUTTON, SAVE AS...) I have try to remove all my PCI card except my SoundCard and Tv-tuner and i have the same problem! i know about the electromagetic in PC but i made some lost of test and i dont know what can i do now! I check for changing my card. 1-MSI Tv@Nywhere (some poeple tell me too much new (driver problem etc..) but i ear about the quality is very good (but in capture?) 2-Zoltrix Tv Genie Wonder PRO 3-ATI TV Wonder I want to watch TV in STEREO!,RECORD with full resolution with using IUVCR (Mjpeg or HUFFYUV),with a remote! Thx !

Yea, this is common with VIA chipsets and onboard sound. Unfortunately, there isn't any sure way to cure it. It most likely has nothing to do with your capture card, though. Some things you can try: 1) if you have onboard sound, disable it 2) could be an IRQ conflict...change PCI slot of sound card 3) if your capture card has audio passthrough, bypass it and try going direct to the line-in on sound card 4) use a different sound card (this _should_ fix it) I had this problem on my old computer, and it drove me crazy! I spent weeks trying to find the cause, and eventually gave up and bought a SBLive which worked perfectly. cjv

Thx ! 

Ok now its my test number 5 (i have tested 4 pc before this one) and all the 4 pc having this probleme!!!!) Pc #1 Soundblaster Audigy Pc #2 Soundblaster Live Value & Onboard Sound Pc #3 Onboard SIS Sound Pc #4 SoundBlaster Live 5.1 The test Number #5 i have seen when my Tv-Tuner is Un-Pluged (just my Sound Card and Video card) when i OPEN the LINE-IN! (no connection in the line-in) i ear the same Sound, but less loud! If with 5 PC i have this probleme! Why Creatives or PINNACLE (and all other compagny) dont talk about this problem!

With all due respect to cjv, I don't think it has anything to do with Via chipsets or on-board sound. I have on-board sound disabled an have always have. I also have a Soundblaster Audigy Platinum sound card. I think it has everything to do with the capture card. Some circuitry and components sit too close to something else on the capture card and picks up something it shouldn't. :-) I had the exact same phenomena on my captures until I plugged the audio from the satellite receiver (or VHS, or whatever my source was) in *directly to the sound card*, instead of passing it from the capture card to the sound card. Doing this will of course mean you'll lose the ability to use the tuner on the capture card. But that annoying sound is gone. /Swan

Ok Thx 

Ok thx your idea is very great i dont know why i dont think about that!.. and for the tuner i can use the tuner in the VCR! ;-) testing tomorrow! I give you some new soon

Hi Wario. You might try to disable the MIC-input in Voulm-settings, if you not already has done it. But i belive that Swan is right. dilbert
