FLAC 96khz plays back at 48khz
#1
I am trying play back a 96khz FLAC audio file via my DAC. Playback in XBMC shows 96khz, but the DAC shows 48khz. I do get audio, but it sounds like a record being played back at a lower RPM. Not sure where to start troubleshooting?

Any suggestions?

Thanks

Is your hardware able to play sound at speed greater than 48 khz ?

Most of audio hardware are limited to 48 khz.

My DAC supports 96khz (see DacMagic). Are you talking about the hardware XBMC Live is running on?

On my Asrock ION 330HT it works fine, at least using HDMI to a Sony AVR, which shows 96 kHz when playing it.

I didn't see your signature. Your hardware can handle a 96khz rate.

As PatrickVogeli noticed, do you use HDMI ? I'm not sure spdif output can handle 96khz rate.

Hm, I am not aware of any spdif/optical Khz limitations. This wouldn't make any sense, since the DAC only has spdif/optical/USB in and does support 96Khz.

Currently I am using a laptop with a docking station for playback. The laptop is docked and connects via USB, but I am not aware of any limitations on the USB end either.

Huh

Geez ... I figured it out. I had to change the Audio settings (XBMC) to Audio Ouput: iec958 and select the correct source on the DAC, duh.

Thanks
