I am trying to set a 2.2 setup with Audiolense and Roon’s Convolution engine. I am not getting any sound from the subwoofers, only from the main speakers.
I did everything as described in the quoted post above, but I have 4 more config files that start with a 6 instead of a 2. So the editing as described in the quoted post above did not work, I got an error code in the Convolution window.
My setup is:
Mac (Roon Core) - USB - Motu Ultralite MK4: 1) Computer Audio 1 and 2 going to SPDIF 1 and 2 and a Weiss 202 DAC that powers the main speakers SPDIF 1 left, SPDIF 2 right); 2) Computer Audio 3 and 4 going into the Analogue outputs 3 and 4 of the Motu and then into Sub 1 (left) and Sub 2 (right).
I grabbed the dropbox file and have passed it along to the tech team for analysis. I’ll be sure to update you when they have had a chance to take a look.
The ones that I am using in the Zip folder across various sample rates look like this (example 44,1) and is labeled “t-ms181016_preferred_linear_phase f-ms181014 m-ms181018_wilson_2sub_motu_2.0 18 okt 18_08 372.0_441.cfg”:
As said, this allows me to play everything at least at 44,1.
But there is also another cfg file for 44,1 that is labeled “t-ms181016_preferred_linear_phase f-ms181014 m-ms181018_wilson_2sub_motu_2.0 18 okt 18_08 375.1_441.cfg” and looks like this:
Can you confirm the behavior you are seeing when playing sample rates > 44.1 kHz? In Roon’s signal path, does it show the Convolution Filter stage with the appropriate number of paths and taps? Do you notice any difference in Audio MIDI Setup when playing 44.1 kHz vs 48 kHz and higher besides for the sample rate changing under the “Format:” heading?
Yes. I can ONLY play 44,1, nothing else. When playing something else (i.e. a mixed sample rate playlist) the sound stops and I need to reboot the DAC. Here‘s a screenshot:
I got it. I am sorry for keeping you busy, it was the missing consent from an older installation of another MOTU unit (Ultralite MK3) that prevented the unit from proper sample rate switching. You basically hinted me towards this by aksing me to look into the MIDI set up. There I found out that when manually setting the correct sample rate, the system would accept convoluted input from Roon.
It is a Mac High Sierra problem - if you do not give consent for third party apps/software within 30 mins, it will remember the brand and not allow you to properly install later or other versions of a manufacturers software.
I got it fixed now, and even upsampling now works.
The only thing that does not seem to work is MQA content - but so far I have only checked “Ben Howard - I forget where we were”.
What happens if you disable the MQA Core Decoder in device setup -> advanced settings? With the MQA Core Decoder disabled, Roon should be operating on the original 24-44/48 file without any MQA operations involved.
