Try re-install the ASIO driver that comes with the DAC and try native DSD again. Also try DoP and see whether your DAC can accept it; You DAC must able to support 705.6k for DSD256 DoP transmission otherwise you are stuck using native DSD.
In native mode: Any other formats play fine. Including: Roon MQA tracks 96kHz, 88.2 any FLAC formats up to 384kHz. Just no DSD formats. Neither DSD 64, 128 nor 256. Roon always complains about lost Audio device
When I switch from native to DoP then I can play DSD 64 and DSD128 (the front of my Mc shows DSD64, 128 rather then the PCM equivalent transport frequency.) just no DSD 256 since Roon does the conversion to 128.
Just had a conversation with the McIntosh support rep.
Here is what he wrote: “Your MHA150 will play DSD files up to DSD256. That said, very few music programs will support this. We test with JRiver and have no problem playing DSD64, 128 and 256. You may want to reach out to Roon tech support and see what they say.”
I confirmed, JRiver plays DSD256 like a charm using bitstream and ASIO. Does this point to a Roon issue?
We’re in the process of reaching out to McIntosh to see if they’ll assist us in getting this issue resolved for you. Since we do not have the hardware on hand, it’s difficult to diagnose what exactly is happening here. I will be sure to update you when we have more information.
I also bought the MHA150 yesterday and still have the same problem in 2021!
On my MacBook Pro 16" (2021, M1 Max, 64GB) I can’t use the device setting as max DSD256 but only DSD128
On my PC I have the same problem as described above with wasapi 32Bit/384khz and DSD128. Under ASIO then only 24Bit/384khz but then DSD256. Why not under a 32bit/384khz AND DSD256? Problem of ROON or McIntosh?
