Roon Android Apps (ARC / Regular) - USB DAC detection and Re-Sampling

Roon Software Discussion
22

The good thing about doing a dedicated USB driver for USB DAC in android OS is it can passed native DSD without having to use DoP in iOS. This is plus benefit. Similar in UAPP. Looking forward for this implemention soon.:relaxed:

I agree with GoldenSound, I’m a disappointed too. I have bought a USB DAC to use with ROON ARC and I noticed everything was resampled to 48 kHz… :frowning_face: Thank you to Prashant_Sistla for his post, because without this, I could have spent many hours trying to fix a problem due to ROON ARC limits, and that cannot be solved at the moment. And thank you to GoldenSound because I did not know USB Audio Player Pro, nice to use it with Qobuz streaming or DSD files.
I hope ROON will react quickly!
Best regards,
Sylvain

Hi, i still use a LG V60 because of the headphone jack AND its internal 24/96 DAC. But, I also use several usb-dacs like AQ cobalt, Cayin R2R and ibasso Dc4. So, it really is a must to have ARC recognise usb-dacs like USB audio player does. Roon stands foor high quality sound in the living room, and i am a great fan of it and use it daily. So please, fix this asap.

But you don’t use your phone in the living room, do you? Also, 44.1kHz and 48kHz are not exactly low quality.

Hey Brian, could you please tell us, where is this feature located on the dev roadmap? Q1 or Q2 2023? Slight off topic, is there a plan to push the listening statistics to arc interface.And a question to that, if I play music via arc I guess the stats get accumulated in the core, right? Thanks in advance!

Check out the latest early access version. It answers your question.

Thanks but I prefer to stay on the prod release channel. Not an early adopter.
So the feature request it’s going out q4 2022 ? If so, that’s very sweet :slight_smile:

Depends on how stable it is I guess.

Hello, Roon Team worked quickly! With ARC 1.05 (30th of November 2022) USB DAC FiiO KA3 works with Roon Beta USB driver. The only problem I noticed at the moment are noises coming from the speaker of the phone just before music starts and when you stop playing. But everything is played losslessly, .dsf files and PCM files. Congratulations!

What is the firmware version of your ka3? You can check that from fiio control app

I tested it with my Helm Bolt and seems to work well. Played a few hi res tracks and dsd tracks without any issues. Have not spent a lot of time with it to check for bugs but so far so good :slight_smile:

Hi,

I tested Roon Arc 1.0 build 111 with an AudioQuest Forest USB-C to USB-B cable connected to the USB input of my Soulution 330 DAC using an Android tablet Samsung Galaxy Tab S7.

Unfortunately, I’m unable to get sound when using the beta USB option in Roon ARC settings. The Roon signal path does show ‘Lossless’.

I tried some settings which Android developer options provide, but nothing helps.

Normal android usb AAudio does give sound, but it’s not what I want because it’s resampled.

Does anybody have ideas to make this work with my DAC?

Thanks and happy holidays
Piet

I also tried UAPP with my DAC but it doesn’t work either, although it does give sound for a short period after which the USB connection keeps failing.

The USB interface of the Soulution DAC is from Engineered.ch, here USB stereo playback interface - Engineered Electronics

Hoping this high-end USB interface will be supported soon.

Happy days!
