Windows 7: Low bit rate only available for a high definition audio device.

cornflakeboy · 06 Sep 2012

I have a PNY 570 gtx videocard hooked up with a HDMI to monitor. No matter if I connect it to a audio receiver or to the monitor I only get a maximum of 2 channels and Bit Depths 16-bit.
Sample rates are only shown as 44.1kHz and 48.0kHz and the HDMI jack only shows L and R. It wont let me test a surround sound speaker system. The stats to this video cards sound will allow much higher samples and bits.
All this information was gathered in the Windows 7 sound properties.

I click on advanced in the sound properties and still cannot change to a higher quality that 48000 Hz.

What is wrong and how to I fix it?

First, 48Khz isn't going to give you any more. 16 bit/44.1Khz is "CD Quality". 48 Khz is usually only used by recording studios that are developing audio for Video use so it will sync properly. I have a recording studio and only use 24 bit 44.1Khz for the majority of my recording (and mix down to 16 bit 44.1Khz for the final product).

The PNY site doesn't list what the HDMI audio specs are for this card.

alright so I reinstalled windows 7. Still giving me lower sound quality options. So I went into the living room and hooked up my computer to the sound receiver which is connected to the TV. I got 5.1 sound with 8 channels possible.

I come back to my room, hooked up my computer to my monitor (that has speakers in it but I do not use because I put my good speakers connected to the headphone jack) then hooked up my speakers to the monitor and still get the same low quality sound.

I guess its only detecting my monitors speakers and not the speakers connected to the monitors headset jack. Is there a way around this?

You can only have one "default" audio playback device, either your "speakers" (PC sound card), S/PDIF Digital or HDMI.
