SO I have the Oppo 205 and have the Max sample rate set to 768 but when I’m in the DSP settings it only allows me to go up to 384K. Does anyone have a reason to why this is?
I’ve also asked in the Oppo section how to setup Roon to play MQA and which driver to use, WSAPI or AISO and I can’t seem to find a clear answer. Does the Oppo Decode and Renderer or just Renderer MQA…?
Can you please confirm that you are using the newest firmware on your Oppo 205? Please make sure that your USB DAC Firmware is up to date and the drivers for it are up to date as well.
Both are listed on this page here:
The Oppo 205 is a MQA full decoder but MQA USB HID is not supported when using ASIO mode, so you won’t see this information in the signal path but you will on the Oppo’s side when using full decoder mode. Further, if you are making use of the WASAPI drivers then the output limit is 192kHz.
I would set the Oppo 205 to Decoder & Renderer as mentioned by John in this thread:
Thanks for posting those. From those screenshots it appears that MQA content is working as expected and reaching the Oppo just fine. The reason why you are not seeing the “MQA Full Decoder” stage when using ASIO is because as previously mentioned, the Oppo UDP-205 does not have HID support on ASIO (as in it can’t report the unfolding in the same way that it reports for WASAPI). Since the decoding & rendering happens internally on the Oppo that path is expected.
I am not sure I understand your original issue of the Oppo being unable to play 768kHz content. Can you please post a screenshot of the Signal Path when trying to play a media file with that content?
Ok the 768Khz is when using WASAPI as my driver and setting the max PCM to 768Khz in the device setting and then trying to use the Roon DSP and up-sample the max setting 384Khz and not 768Khz. Is this normal?
When we took a look at this device in the lab, the limit for the WASAPI driver was 192kHz so that is likely why you are not seeing that option listed. I would suggest using ASIO drivers for the higher bit-rates.
