| 486675 | 2006-09-22 08:18:00 | Yes...I am back...Now i have succeeded in recording sound from tv into my pc as instructed, but now i have a problem...the recorded volume is very very low such that even after increasing the volume option(increase by 25% option in the sound recorder) a couple of times(after three to four strikes the volume becomes completely nil) i could hear only low with the headphone with a big hum sound associated with it...what 2 do....PLEASE HELP!!! | sleuth (11045) | ||
| 486676 | 2006-09-22 11:13:00 | Did you test the sound volume on your TV? I know (from past experience) that if the sound on the TV has been muted, or turned down real low, the sound volume on my PC's hard drive will also be very low. |

| 486677 | 2006-09-22 12:05:00 | TV sets usually use a "floating chassis", and often have no "earth" lead, on the 3 pin power plug, because you are unable to ground anything in the TV, the entire electronics is at quite a voltage due to the way they work (it's cheaper to make them this way). Audio sockets etc may be decoupled by capacitors to give safety, but it still creates a 50 Hz (probably 100 Hz due to full wave rectification) underlying ripple or "hum" on the signal, but only when its connected to another "earthed" device such as a PC. It's "ground loop hum" Nothing easy can be done in many of these cases. Use a TV card in the computer instead. Using a mis-matched set of connections (speaker or earphone output on the TV and Mic or Line in on the PC) will not help with any latent hum either. You need an impedance match, AV out on the TV (if fitted) and Line in on the PC is the correct match. |
