MediaPortal Audio renderer - better video playback quality (5 Viewers)

[robyf]

Other way round - I'm using a newer driver which was released to cure some HDMI issues. Must have dropped functionality for it, I'll have a look and see if robyf has posted results and compare.

Not yet but I will post them as soon as I can.

AW: MediaPortal Audio renderer - better video playback quality

I have some flv-files where the sound is muted if they are played through the MediaPortal AudioRenderer. The renderer connects successfully with the FFDShow audio renderer but there is no sound. The files can be successfully played with DirectSound. I suppose that the Renderer does not detect that the audioformat is not compatible so it does not switch automatically to DirectSound.

Look at the attached logs.

WASAPI device / driver accepts the format so the issue cannot be incompatible audio format.

Please upload a sample file.

Nope, ReClock polls for better compatibility.

Yep, as I expected. Down side is a bit more glitch prone (on high CPU loads) and a bit higher CPU load. But those aren't something to be discussed in this thread.

Please test if you can reproduce a crash with audio stream switching - at least I'm able to cause random crashes when changing audio stream (TV / DVD). I'm currently working on sorting out that issue.

AW: MediaPortal Audio renderer - better video playback quality

Hi,

I checked the Realtek HDMI Driver with WASAPI test.

Here are the results:
WASAPI-test.exe version: 3 tested: 2526 ok: 189

I attached also some logs with the newest renderer version.
I get sound, but only limited to 2.0

For some reason EXCLUSIVE: on EVENT DRIVEN: on combination is not supported at all by that driver. Please change WASAPIUseEventMode to 0 in registry.

Looks much better and now I get 5.1 sound.

I will test a bit more...

Some logs, the last two are with the FLAC 7.1 Testfile.
24 Bit output limited to 2.0
16 Bit all 7.1 channels

This are my results of wasapi_test with ION (nvidia) over HDMI:

For people who have problems with ION here's my codec setup:

- Install SAF5
- Install powerdvd9 codec

TV Codec: mpeg2 microsoft, h264 powerdvd9, audio ffdshow
video codec: mpeg2 ffdshow, h264 ffdshow, audio ffdshow
dvd: mpeg2 ffdshow, audio ffdshow

NVIDIA Drivers: 197.45

I use a 2 channel output configuration in ffdshow (do not have multichannel here) so don't know how it behaves with multichannel.
