My first initial test did not work.

What i have done: I rooted the device ( so I am in standard rom 4.2.1) installed the trinity kernel, and your two zip files ( and the trinity instead of the CM10 kernel). No sound in the FIIO yet. Is there something I have missed? Do I need to also install another ROM - I thought that the trick was the kernel.

I will be willing to test what you like, so can you give me an advice of what to try?

my next try was to install cm - I took the newest version, which apparently was a mistake. The installation went fine, but when I added the audio mod, it got stuck in the startup cm animation. Just to clarify - the CM version you are using is it a 4.2.1?

Same here:
  • stock rom 4.2.1
  • rooted;
  • latest trinity kernel
  • flashed both zips
  • sound either works over speakers or over usual headphone jack but not over DAC
  • the tested soundcard is an asus xonar u3
Thank you very much for your work. I'm highly interested in this project and a solution for my problem. If this would be implemented in CM10/AOKP it would be a great feature. Greetings from Germany

Thanks for the input.

As previously mentioned changing the entire services file is probably not the best solution as you have seen it has caused a few roms to stop responding. As for things not working entirely I am not sure yet.

I will attach the separate service soon, providing I can get it to work reliably so you can test without having to change the services file.
If that doesn't work out I will attach a build with more logging enabled so we can workout what is going on.

That sounds great. Can you say which version of android (CM) you working successful with ( 4.1.2, 4.2 or 4.2.1?).

All the best

I can really get nothing to work. I installed a 4.1.2 rom, with the appropriate trinity, modded the asound.conf, but with no sound out.

I then also tried to but the pcm.usbdac command into a newly made asound.conf in the 4.1.2 rom, also that did not work. What am I doing wrong??

Not working here either:

- M-Kernel
- 4.2.1 stock rom
- flashed both zips

USB DAC works with M-Kernel when Nexus 7 is booting with DAC connected, tested with Nuforce uDac 2 and Atoll DAC D100
Samsun S3 works on the fly, just plug in OTG and DAC and it works, remove and speaker sounds.

But your S3 is running a Samsung ROM?
My S3 with CM10 wouldn't work with my DAC. I had to flash back to stock Jellybean to get DAC working.

I would love to get CM10 and DAC working on my S3!!!

Thanks for all your hard work. It's great to see progress on this.

I tried on my Nexus 7 running the latest Faux kernel, stock 4.2.1 ROM. I plugged in a generic USB headset, with volume controls and a power on//off button. When you first plug it in, the volume buttons actually controls the Nexus 7 volume sliders! Very cool. But when you power the headset off and back on, it loses the ability.

As mentioned in the thread, hotplugging doesn't work. When you boot up with the USB headset connected, it works great.

Hahhah, whatever you guys do... don't flash these files on a Galaxy S3 !!!

Hard bricked my phone. No display, no turn-on buzz, no download mode... nada!

Ahh well, I shoulda known better than to flash kernel files meant for an entirely different device on my S3. I just really, really wanted my S3 and CM10 to work with a DAC!
