Been searching for days on Internet for this issue, without luck :(
I own a Teac UD-H01 : when connected via USB => crackles and clicks
Which tool are you using in userspace to test this? Did you try aplay?
optical => no problem
I'm confused. According to
http://www.teac.com/product/ud-h01/
there is no optical output. Are you saying things only work if you connect an optical input?
Are you absolutely sure that you're not dealing with analog audio distortion? IOW: did you try the very same setup with a different OS?
I want to use it as USB because it's asynchronous, so only a few jitter
I don't follow. According to the device specs, USB is the only option to connect this thing?
I've tried many kernels (3.12.7, 3.12.6) and the LTS that I use normally (3.10.25, 3.10.26) : not solved
I've tried on a fresh ArchLinux install : no way I've tried Xubuntu : not better (plus they use pulseaudio) I've tried on my desktop's Arch Linux
I'd like to know if any of you have a patch or a fix for the Tead UD-H01 DAC when used via USB
The device exposes itself as USB audio v2 interface, so it should work out-of-the-box. What's interesting is that there are two clock sources, but only one is connected in the topology (bCSourceID = 12), and there is no clock selector. Crackles could be related to wrong clocking, but that's just guessing.
Please check whether the device works under Windows or Mac OS X.
