Hello everybody, I have Denon AVR-2307CI (Audio/Video reciever) with me. I am feeding graphics card's output to the HDMI input for Denon reciever. Now the problem is the sampling frequency of the signal is stuck to 48KHz on Denon screen. I tried changing the sampling frequency of signal using sound card's control panel (Sound cards tried: X-Mystique and M-Audio) but it didnt help . Can anyone help me on this issue ?? Note: The sound card supprots 44.1KHz, 96KHz frequency rates. Again, is there any other way to find out whether the sampling frequency of signal is changing or not ?? I just want to measure the sampling frequency of audio signal (wheather it is 44.1,48,96 KHz). But the problem is I am having HDMI singal which has audio+video. Just a drop a email to rpawade@gmail.com Waiting for your replies..

If the settings of the sound card change, the spectrum of the recorded signal should show this as the tone moving between different relative frequencies. Rune
