Sizzling when streaming from Qobuz with 192 kHz quality

When streaming from Qobuz with 192 kHz/24 bits, or even when reading files bought on Qobuz with this Hi-Res quality, I have some sizzling, sometimes strong.
My DAC is able to handle such Hi-Res quality files (the screen indicates 192 kHz is recognized).
My Qobuz subscription is Hi-Res 192 kHz.
As soon as I change the frequency target to 96 kHZ in Audirvana, there is no more sizzling.
Please see attached debug info.
What could be done to avoid this ?

Hello @Pholoppe,

Have you tried to deactivate upsampling and try again?

Hello Damien,
I guess you’re talking about that

If yes, I did it. No change, still some sizzling.

Hello Damien,
I deactivated upsampling (please see the reply I sent yesterday, to be sure I did it at the right place). No change, still some sizzling.

Do you have any idea how to suppress this sizzling ?

Have you tried to disable Software volume control?

Can you please tell me how to do this ?

You can disable it by going in your output settings in the audio volume section of Audirvana.

Thank you for the explanation. I did it. No change, still some sizzling.

Have you tried with your MacBook Air speakers? Do you have the same issue?

Actually with MacBook Air speakers (and with headphones too) the output frequency is 96 kHz. It’s not possible to have 192 kHz as output. Result is no sizzling with MacBook Air speakers and headphones.
By the way I made the following test with the DAC : I selected the “by frequency” option for the upsampling, and I selected from 192 kHZ to 96 kHz as target frequency. With this configuration there is no sizzling. So the problem is really when the output frequency is 192 kHz.
Does it help ? What to do ?

Hello @Pholoppe,

Do you have a 192khz file in your local library?

Yes I do. And I made the test reading this local file. There is still some sizzling.

Hello Damien,
Any idea to get rid off this sizzling with 192 kHz ?
Thank you for your reply.

I just installed Audirvana and am having the same problem with “sizzle” when streaming 192k files from Qobuz. Tried the suggestions above but also did not work for me. I’m connecting via USB Toslink to the DAC in my Yamaha A-S 501 integrated amplifier.

Thanks for any help.

Hello @Pholoppe,

If you try to play a 192 Khz track from Qobuz player without Audirvana, do you still have the issue?

I do not have the issue when playing directly from the Qobuz app, however, I was able to get it to play properly from Audirvana by connecting my laptop to a different DAC.

I have resolved this “sizzling” issue by turning off the “Use Large WASAPI I/O buffer” setting. 192 kHz files now play without sizzle or static.

Hello Radiohead,
How have you turned off the “Use Large WASAPI I/O buffer” setting ? Where is it ?
Thank you for your reply.

It can be found in the Low Level Playback Options section of the settings for your DAC.
