Multichannel over HDMI: "could not be started on WASAPI using '96kHz 24 bit 6ch'

(1/5) > >>

JJJ:
I'm having trouble with this. (Also with Zoneswitch to manage output paths for stereo versus multichannel but I think the below is the root of this problem.) I have a Theta Digital Casablanca III HD connected by HDMI.  In JRiver, I am using WASAPI, with the Device set to default (I don't see anything resembling the Theta CB listed under devices). (Disable event style makes no difference.)  The CB III HD can handle multi-channel audio over HDMI from a wide range of sources.  However, if I try to play a 5.1 ripped DVD-A disc that I own (with the audio tracks converted to ALAC) I get the following message:

Details:
Playback could not be started on the output WASAPI using the format '96kHz 24 bit 6ch'.

The mixing format of your hardware does not support the current output format.

Please use the 'Output Format' tool in DSP Studio to convert to the mixing format listed below:
Sample Rate 48000Hz
Channels 2
Bits per sample: 32

Why is it recommending a conversion to 48kHz, 2 channel and 32 bits?

It's a hardware issue with your PC. Cheapest solution is to buy something like a Radeon HD7750 GPU http://www.amd.com/us/products/desktop/graphics/7000/7750/Pages/radeon-7750.aspx  and use it for the HDMI output. It will give you all of the sample rates like 24-176.4 for SACD. Not all hardware supports all sampling rates. I believe the one you have is only capable of 48khz-2 channel. Theta's going to support high resolution in the next upgrade so you'll want a sound card or sound from GPU capable of 24/88 and 24/176 for SACD.

Hmm. Thanks BD. I need to check the spec of my current mobo (my final build will use a different one but I'm waiting for Haswell).  It is meant to handle high res HDMI.

JJJ:
This is my current motherboard which would appear to support high definition multi-channel audio.

Still stuck with this.

When I look in Control Panel -> Sound -> Playback I see a number of options. There's a few that relate to my Juli@ card, others that relate to RealTek and then HSRS which is Intel Display Audio. For each, when you double-click on them you can see the "Jack Information".  Only HSRS has a jack related to the HDMI port "HDMI Digital Jack".  The RealTek ones are linked to ATAPI Internal Jack, Front Panel 3.5mm Jack, Rear Panel Optical Jack.  The problem with HSR5 is that while it supports a lot of bit depths, sample rates and formats, it is limited to 2 channels and the encoded formats it supports are all related to DTS and Dolby Digital. When I play a stereo track via WASAPI to HSRS, JRiver will play the tracks.  

When I look at the specs of my mobo, I see "10-channel (7.1+ 2 independent multi-streaming) audio subsystem using the Realtek ALC892* audio codec". What I don't understand is why I can't get a Realtek option that uses the HDMI port.

Anyone have any ideas?  


UPDATE:  I even have problems with stereo tracks with HSR5. Playback was working and then sound cut out (the track was still playing in JRiver).  I could not get sound to restart despite JRiver playing the tracks ok.
