Edit. Some additional info. The above tests and logs was using a Topping E30 USB DAC.
For UPnP using an Ultrarendu. Tested on Audirvana Studio with real time mode turned off.
On Windows, it takes about 30 to 50 seconds from the time play is pressed and before sound is audible, with the front part of the track cut off. However, the audio is bypassing convolution. Turn realtime back on and audio starts right away, but convolution is bypassed.
On Mac, takes about 30 seconds to hear audio from when play is pressed. But now convolution is working. Turn realtime on, audio starts right away, but convolution is bypassed.
So for UPnP, on Windows convolution is bypassed, but works on the Mac when realtime mode is off.
Updated logs sent along with a convolution filter with all the high frequencies rolled-off so one can easily tell if convolution is working or not.
I am having a similar issue. HLC is bypassed if I do not have real time enabled. I’m using ASIO drivers so no network stuff going on at all. HLC is also processing at the upsample rate if I have that turned on. Shouldn’t the upsampling be taking place after the vst processing? At least that’s how it’s shown in the signal flow.
I’m on a windows 10 machine. Usb out to an RME ADI-2 PRO and Geshelli JNOG2S.
I know you are sexy, but, can you give me the link to Studio v2.9 ?
Ok, joking, don’t stay with old Sonoma…
With macOS usually first stable version is like .3 version,
update to last and see… might won’t change anything, but
.3 version and later seems like more stable version…
