There are quite a few topics on this so trying to condense down to understand the issue on my system.
I have a Late 2014 i5 MacMini as my Roon Core connected to my Oppo UDP-205 via the USB DAC. The Oppo is connected to my Marantz SR7011 via analogue interconnects. I am running 2-channel only.
The signal path on my iPad is telling me I am running all ‘purple’ lossless but on my TV screen, I am not seeing MQA appear in the top right hand corner as others have shown and the signal path appears to be limited to LPCM 2.0 48k.
My Mac is also defaulting to 48Hz so appears to be preventing higher signal paths.
I am wanting to check the settings for both my Roon device set-up as well as those within the Oppo and confirm the Late 2014 Mac Mini is capable of allowing the MQA signal to pass to the Oppo via the USB DAC.
Any help on this issue would be very much appreciated!!
My first comment is to change your Oppo’s Output volume from Variable to Fixed.
The Signal Path shows that it is leaving Roon and going to your Oppo just fine. You have set Roon to send the file untouched to the Oppo and it is doing that. The Oppo should be doing the full decode, but, it is not.
Is your Oppo’s firmware up to date? You might also take a look at this thread…
Thanks for the help with this as I now have the problem sorted.
As per the feedback from Christoph, my USB DAC Firmware was out of date so I followed the instructions from the Oppo website as follows:
Some minor teething issues as my Mac Mini is running macOS Catalina and the downloaded Firmware Upgrading Tool supplied by Oppo does not appear to be supported. Luckily I have an older MacBook Air running macOS High Sierra so after connecting this to the Oppo vis USB, the update worked perfectly from 0112 to 0115 to 0118.
After this process, glad to report I am now seeing the Oppo decode MQA successfully as per the below pictures:
