I fail to pass native formats to Chord Mojo over USB.
With same connection and phone settings USB Audio Pro recognises the Mojo (by name) and happily passes on native formats from Qobuz and switches between sample rates. Arc converts all rates to 48kHz.
(@Suedkiez - I understand you also have Fairphone 4 at your disposal. Any more succes with native USB playback, or suggestions on something I could try?)
Example with 96/24 source from Qobuz
Arc/Roon (note that Arc sees output as AAudio, so perhaps not surprising that everything gets resampled?)
Hi Ozzie I was having similar problems to you, but my audio for the FIIO KA2 is all working through USB as per your post, but Roon is downsampling to 16 bit for everything.
Can you check your signal path and check that Roon is not downsampling the audio before it sends it to the DAC which is what mine does.
And checked with an existing short playlist used for previous testing of sample and bit rates with different DACs. The path in Arc and the light on the Mojo suggest all is well with a range of 24bit tracks from Qobuz (But as mentioned before, there is a pretty horrible pop over the phone speakers on almost every transition)
Yes thanks yours is doing exactly what I expect it to do.
Though Mine is sounding good so I have no complaints about that.
I am guessing my KA2 is not fully supported for 24/96 on Roon USB driver, I did ask the team what DACS are supported to what level.
I’m using bit perfect USB output via Arc successfully on my old LG6 using Android 9 with an Audioquest Dragonfly Cobalt. Initially, the volume is briefly maximum, but I think that’s a Dragonfly problem.
It sounds great. Thank you very much for implementing this. It makes me much more likely to use Arc while I’m away from home.
Using a relativly cheap usb to 1/8" adaptor cable with a built in DAC Chip (dosmix) . currently getting 192khz at 24bit and then its doing a 64bit float to do the volume leveling and final playout is 192Khz @ 32bits out of my google pixel 5. Sounds fantastic, but occasionally freezes or pops but not to often and for first beta version very impressive. The is also occasional volume changes. What i cant get working is the DSD albums i have , which are owned in my library. it shows those at 192 khz / 24 bit and wont even show the dsd versions. show maybe just trying to push this to far to soon…
