Managed to get bitperfect! (1 Viewer)

[burken]

Thanks a lot for the PureAudio/ASIO Music Player plugin! I have finally been able to get bitperfect audio with MediaPortal using the plugin.


I have the following equipment/software:
Windows Vista Ultimate SP1
Realtek HD Audio (with 44.1 kHz support)
MediaPortal 1.0.0.0
ASIO4ALL 2.9
PureAudio 0.2.0.2

I can play a DTS 44.1kHz-encoded WAV file and my amplifier detects that it is DTS and play the music without problems. When playing the same WAV file without PureAudio I just get noise so I am quite sure I get bitperfect audio with PureAudio.

It took some time before I got it to work though. First I didn't get any audio at all, just silence, no matter what music files I tried to play. In the settings, PureAudio uses the labels "First channel" and "Last channel" and that confused me a lot in the beginning. I tried a lot of combinations but I didn't get any sound. I enabled and disabled devices in the ASIO4ALL GUI but I just didn't get how I was supposed to configure the audio devices.

It was not until I downloaded and tried out Foobar2000 with ASIO4ALL that I figured out how to configure PureAudio. The ASIO settings dialog in Foobar2000 (ASIO Virtual Device Editor) is easier to understand. You can map a device to a channel with easy to understand names like "left", "right" etc and you can also play a test signal to help identify the device. This helped a lot and I was able to see what device corresponded to my SPDIF left/right signals. I think it would help newcomers to PureAudio if the settings interface was the same as in Foobar2000.

Edit:
After playing around some more I have realized that I don't get any sound from the PureAudio plugin (via SPDIF or analog) if I don't disable the HDMI audio device on my ATI graphics card in Device Manager.
And while Foobar2000 is good for understanding audio device settings, I have not been able to get bitperfect sound in Foobar2000, only in MediaPortal.

Congrats!
I'll have a close look at foobar to see if i can learn from it

I have filled in System Specification now.

The Realtek audio I have is the onboard audio device on my motherboard, Gigabyte GA-EP35C-DS3R. It is a Realtek ALC889A device. There are variants of this audio device, with or without built-in DTS support. I have the one without built-in DTS support and it supports multiple sampling frequencies. For comparison, in the manual for the motherboards with Realtek audio with DTS support, it looks like these devices only support 48 kHz.

I am currently using the RCA digital output connector.

Damn. Realtek even started with variations within same models?

I also have the 889A. I believe Gigabyte is the only one that uses it - asus uses 1200-something IIRC. I have the 690G mobo. Will try to get bitperfect when I find the time, although I believe my mobo supports DTS.

here is screen of my ASIO setting in Pureaudio. I am trying but still get no sound
Please help me

 

[nmt1978]

and here is my pureadio configuration. I already disable HDMI audio device, but no sound at all

 

[burken]

Do you get sound with the ASIO4ALL plugin in Foobar2000? It is easier to debug problems in that program than in MediaPortal.

Also, have you set the Realtek Digital Audio Device as default Audio Device in Windows?

These configurations look ok to me anyway.
