I am new to the forum and new to the 5.1 world regarding HTPCs so forgive me in advance if I state slightly wrong details when explaining my problem.
I have a PC which I am going to use as a home theatre system only. To date video has been played out to a LCD monitor through HDMI and sound via a 3.5mm stereo jack to a Samsung 5.1 sound system.
I have bought an external 5.1 sound card with the intention of playing 5.1 encoded movies in 5.1 through the audio system and any music (mp3 etc) in 2.0. It is now connected to the Samsung system via optical toslink cable with the new sound card.
After installing drivers etc for the card, when trying to play back music the sound is jittery. I can only describe it is as jittery every second or few seconds for a few frames duration only. The same problem occurs when I play a 5.1 movie. I am using Media Player Classic.
My friend who knows very little tells me that it may be my Samsung receiver as he thinks it can only receive 48khz signal and all my mp3s and mkvs etc are 44.1khz. He has told me to do some reading up on WASAPI etc in an effort to understand what may be going on. (the receiver is also hooked up to a satelite service which TXs with 5.1 so I am imagining that this 5.1 Dolby is at 48khz.)
From this I have a spent literally a few days reading up on upsampling etc using Reclock and/or ffdshow in an attempt to try and get my audio output from the soundcard in 48khz. I have been trying different settings with these programs and getting nowhere either resulting in more jittery inaudible audio or no audio at all with error messages.
So can anyone help me out and point me in the right direction as to whether I am using the right software for the job and if so how I should go about setting the software up? Or am I looking in completely the wrong area to solve my problem?
Thanks in advance.
