I saw it is in 3.15.rc5, and it works fine for me (TEAC UD-H01). Splendid, thanks! Rutger. On ven., 2014-05-09 at 09:00 +0200, Clemens Ladisch wrote: > Rutger Noot wrote: > > I heard that there is a patch solving the problem with the TEAC USB > > UD-H01. Did that already make

Dear all, I heard that there is a patch solving the problem with the TEAC USB UD-H01. Did that already make it to a stable kernel? For what it is worth, I am now running a stable fedora kernel: 3.14.2-200.fc20.x86_64 and the behaviour has changed. No more clicks, but now there is another artefa

Dear Andrea and list, I had, and still have, the same problem: see the thread "teac UD-H01, bad 24 bit playback" for a discussion. There were other reports (Teac DAC, I've read someone can make it work fine via USB 16/2/44100, but NOT ME...) of similar problems, with the jitter even at 16bit. Thi

Hi, Oddly (and fortunately!), in my case the TAEC works (at 16 bit) with all linux boxes I tried, but at 24 bits it functions only under windows (with the proprietary driver). With all linux machines I tried, 24 bits playback give rise to this clicking. One other thing: the kernel messages you

Dear Eric and list, I have a Teac UD-H01 (I assume that you are talking about that one). It works fine at 16bits/any frequency but I have crackles (much like you are reporting) in 24bit mode (at any frequency over 48kHz). I am not much of an expert (in particular, I'm at loss concerning 24 bit pl

Hi, I have difficulties with the TEAC UD-H01 usb dac. Playback is fine in 16 bit mode (even at sample rates up to 192kHz), but in 24 bit mode there is an incredible amount of jitter (continuous clicking) at any sample rate above 48kHz. Admittedly, there should be little (if any) audible differenc
