multi channel 192khz or 176khz to a amd 5670 via hdmi
« on: January 24, 2013, 02:39:20 pm »

Trying to get multi channel 192khz or 176khz pcm to my onkyo 809 via hdmi using amd 5670 graphics card. I am using wasapi and have tried wasapi event style . everything up to 7.1 96khz works fine. I know the receiver can handle 7.1 192 and 176. wondering if the graphics card audio chip is at fault. Cant find specific information on the 5670 audio specs. Before I buy a new graphics card does anyone have any ideas on how I might get this to work? If it is the graphics card what amd product do you guys recommend I purchase? Thanks. Using latest MC version.

Are you using 720p or 1080p output on the video card? I think you have to use one of these for the higher sample rates to work. If you go to the Windows control panel > Sound > Playback > AMD HDMI Output Properties and the Supported Formats tab does it show 176.4 and 192 as supported formats?

Mojave, thank you for your reply. I am using 1080p as a video resolution and windows correctly reports all possible frequencies as compatible 44,48,96,176,192. as well as all the dts and ac3 formats. On a side note 176 and 192 will work in stereo just not 5.1 - 7.1 I have a feeling it is a limitation of the video card.

I have a TX-NR709 and an AMD Radeon card so I have a really similar setup.

I just tried 192 khz 7.1 output (24-bit with dithering set in the Audio DSP) and it worked just fine with WASAPI Event Style.

You wouldn't happen to have the Realtek AMD HDMI driver installed? That might have something to do with it. The only other thing I can think is if you have a really cheap HDMI cable that isn't offering as much bandwidth as it really should.

Oh, and one more thing. In the WASAPI Event Style settings, presenting 24-bit data in a 32-bit container is recommended for maximum compatibility with AMD cards. I doubt that's your issue, but you never know...

Well it might be a bit more complicated than that. I guess the AMD 5000 series has had a whole litany of problems, just check out this thread....

My recommendation would be to get the latest AMD drivers first. If that doesn't work, install the Realtek AMD HDMI Driver.

With WASAPI event style at least (not sure about regular) buffer size also comes into play. I recently had a problem with my 7750 where it started rejecting 48/24 5.1 (but accept 48/24 2.0 or 48/16 5.1) and it was because I had increased my hardware buffer to 500ms diagnosing another problem. Turns out the 7750 can only handle 48/24 5.1 with 250ms buffer or less. My guess is 96KHz would need a 100ms buffer and for 192KHz I would have to use a maximum buffer of 50ms. Chances are the 5670 would need an even smaller buffer.

Thanks guys I will investigate all of those possibilities. I will play with Buffer size to see if that helps,  I don't know which driver is installed but whichever one is installed I will try the other. Will report with results. Thanks!

I do in fact use 50ms for my WASAPI Event Style buffer size. But I also do have a 7000 series AMD card so as Jong said the optimal buffer size might and probably will be different for a 5000 series.

Oh, and here's the link to find the Realtek AMD (ATI) HDMI driver:
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false

I don't think it should be needed. There was a time when the Realtek HDMI driver was recommended, but I think that for some time now the official AMD HDMI drivers are just as good if not better. I actually had issues using the Realtek driver that were fixed when uninstalling it and going back to the official driver. But you might find the opposite to be true with an older 5000 series card so it's worth a try.

Yeah I was very active in that AVS thread when I had my 5750 and the AMD drivers were very quickly the preferred option.

Fixed! It turned out to be the buffer size, the magic number for the 5670 was .05 ms so far I haven't seen any adverse effects except when I drag the seek bar to far i get some stuttering but I don't seek very often so not a major concern. Thank you everybody for your input.

I was mistaken. seconds not MS Audio settings output mode =wasapi output mode settings\ Buffering= .05s

It's worth trying event driven WASAPI, probably with 50ms buffer, or maybe 25ms. It could give better results.

Jong, That worked as well! Seems to be a bit more stable. I will keep it that way. Thanks for your help.

Good call on the buffer sizes. I didn't know they were THAT fidgety.

oh yeah that info might be useful for someone one day.  50ms is the buffer size that works with wasapi event style.
