Hello Everyone,

I've searched through this forum and the internet and couldn't find anything that could help me sort out my play back problems with high-res audio files 192KHz 24bit via the BDA-1.

I'm playing the files on my HTPC via optical cable to my BDA-1 with no sound for the 192KHz files. Other sample rate files work fine it's just the 192KHz files that fail.
When I play different sample rate files the Sample Rate LED Array changes so I know different sample rates are being received correctly and played on the BDA-1.

Playing the 192KHz files the input LED turns RED on the BDA-1 and no sound is heard. I've also tried my laptop as well via a SPDIF inputs using a coaxial cable with exactly the same results.

Could there be an issue with the BDA-1 or just my setup?

Any help or advice would be greatly appreciated.

Thanks in advance,
Q

Setup
Mother Board = ASUS P7H55D-M EVO - http://www.asus.com.au/Motherboards/Intel_Socket_1156/P7H55DM_EVO/
Driver = ASIO4ALL 2.10 - English - http://www.asio4all.com/ (after doing some research I understand this gives me bit prefect output from my HTPC thru to the BDA-1)
Player = foobar2000 and xbmc (same results on both players using the ASIO driver)

Output
Optical via in to the TOSLINK input on the BDA-1

What works
Sample rates: 32KHz, 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, • 16-24Bit PCM

What doesn't
Sample rates: 192KHz • 16-24Bit PCM

Hi qscott

I can say without doubt it is NOT the BDA-1.  The RED LED means it is not receiving the 192/24 signal from the source.  The Toshlink or the motherboard or the setup may be the problem - is there a COAX out available to try? 

I usually get about a call every 2 weeks or so from customers that have similar issues with high resolution files. That's one of the reasons I developed the BDP-1 Digital Player - been there - done that

The great thing about the BDA-1 is it tells you what is coming IN whereas a lot of DAC's tell you what is going OUT so you do not know if the DAC or Laptop or Computer is doing any upsampling etc.  Sadly there are a lot of people out there that think they are listening to NATIVE HIGH RESOLUTION digital music and they are NOT

Definitely not the BDA-1 as James noted.  I use mine with an HDMI audio de-embedder and have played with various universal transports to take hi-rez PCM from SACD and pass DVD-A into the DAC.  I've gotten the red light on a couple and I've also gotten the sampling frequency to lock with no sound as the particular transport I was using needed an HDMI handshake.

Looking at the MB specs it does not say it supports 24bit/192KHz via optical.  Most optical outs are limited to 24Hz/96KHz.  You might check with ASUS to see.

[Phil A]

I've personally not tried it but the manual would imply, except for the USB, 24/192 is supported by the other inputs - http://www.bryston.com/pdfs/09/BDA1_MANUAL_20090710(4pg).pdf

I use the four coax inputs

While it's possible that some TOSLINK outputs may not support 24/192 or that a marginal optical cable might be problematic, qscott did say he tried it on another computer with the same results (though I'm not sure what kind of laptop has an S/PDIF coaxial output).  And it works with 24/176.4.
 

I've also tried my laptop as well via a SPDIF inputs using a coaxial cable with exactly the same results.

qscott, you mention the "test file" used, have you also tried it with other 24/192 files?

Hi Guy's,

Thanks for the feedback.

I have tried a number of other test files 96KHz and 192KHz via the optical TOSLINK input (HTPC) and the S/PDIF coaxial input (Laptop using a docking station) on the DBA-1 with same results. I'll go back and test for the 176.4KHz sample rate and as it was only a once off test I ran for that, pretty sure it worked OK. Let you know.

I do have other optical cables so I'll try that as well. I just hope something will fix it or I'll have to take up James's solution and pick up a BDP-1 

HAL ASUS do quote that the optical does output 24bit/192KHz via optical, I'm starting to wonder just how true that is.

Also I've used/tested the WASAPI driver and have come up with the same results - http://wiki.hydrogenaudio.org/index.php?title=Foobar2000:Components_0.9/WASAPI_output_support_(foo_out_wasapi)

Will be in touch.
Cheers,

What gives, I'm having similar results?

TV display shows LPCM 2.0 96 khz/24 bit 4.6 Mbps. But BDA-1 only lights up 48K?

I have an HDMI cable going to HDTV and coaxial to BDA-1, downmixed to pcm stereo.
