Public bug reported:
Bus 002 Device 005: ID 0d8c:0102 C-Media Electronics, Inc. CM106 Like
Sound Device connected using S/PDIF optical out.
Playing audio at 44100Hz has clicks and a quiet cyclical noise at
roughly 5 cycles per second. The noise is like a really quiet shaker.
Clicking seems random and of varying intensity.
Affects multiple applications including Rhythmbox and Kodi. Even `aplay`
using a raw CD file copied to disk.
Higher playback rates of 48000Hz are clean and work fine with AC3 and
DTS encoded pass-through. I tested this in Kodi where you can pick the
playback rate with on-the-fly re-sampling. Same sound re-sampled and
played at 48000Hz plays flawlessly, everything at 44100Hz has the
problem.
Previous sound card (integrated) is fine. HDMI output is also fine.
Tried the `tsched=0` workaround, did not work.
