TOSLINK from HDTV resampled to 48 khz ?

post #1 of 3
Thread Starter 

I have the following setup:

 

Vizio 50" HDTV 

Toshiba 42" HDTV

Matrix Mini-I DAC

Macbook pro 2012

 

Scenario 1:

 

Toshiba TV -> TOSLINK out - > Matrix DAC

I tried using both the Toshiba and the Vizio HDTVs and I notice that connecting my Macbook to the TVs generates different results using SPDIF output from both TVs.

When I use the Toshiba TV, I get a 44.1 khz signal on the Matrix DAC, if I choose that from the Audio/MIDI setup and I can also switch this to 48 khz if I wish to.

 

 

Scenario 2:

 

Vizio TV -> TOSLINK out -> matrix DAC

 when I use the optical out from the Vizio, I only get a 48 khz input to the DAC, even when I choose 44.1khz output from the output options

 

How can I make the Vizio output a 44.1khz signal without resampling it to 48khz ?

 


Does anyone else have experience using a HDTV's optical/coax digital audio out into a DAC ? 

 

I am trying to find a HDTV that will not resample my signal to 48 kHz. 

 

Any suggestions would be appreciated.

Is there a problem with just using the 48Khz?

Doesn't the resampling to 48 khz screw up the signal in terms of quality ?
