Outpot sampling rate

[nosferatu]

i have a question about outpoting digital audio from computer to AV via Spdif.

i have an option to output
44.1K
48K
98K
198K

i tryed all of them but didn't notice any diffirance in soud quality.
can anyone explain outputing rate from computer to avr

The sample rate is the number of samples per second; eg. a CD contains 16 bit / 44.1 kHz PCM which means 44,100 16 bit samples (numbers) for every second of audio.

If you set the output of the card to a rate that is different than the source it will resample and in general there is no benefit to doing so for playback. Resampling involves interpolation, in other words 'intelligent guessing', to create more samples in between the original ones so that there are more. There can be a small benefit in that quantization noise is pushed into higher frequencies but it is very difficult to really hear any difference as you've noticed.

If you are passing DD or any other encoded digital format you do NOT want to resample as resampling will destroy the encoding and the AVR will no longer recognize it as DD.

I find a little bit of a difference in the overall sound between the 44.1 and 96k modes on my yamaha receiver. In most cases people won't notice a diff. but in my case it is very subtle, but the highs are a bit cleaner and the bass is just a bit less muddy and more defined. Might just be my soundcard, im using a realtek that came with my HTPC

Wait a minute here - I thought you wanted me to rate the pot samples you were sending out?

i have realtek too and for some reason i can't output DTS or DD the only think that work if i play mp3 or anyother audio. anyone know if there are extra steps i need to take to have DTS and DD go to my AVR
