2015-09-20 14:28:30 Phill description Bus 002 Device 005: ID 0d8c:0102 C-Media Electronics, Inc. CM106 Like Sound Device connected using S/PDIF optical out. Playing audio at 41000Hz 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 41000Hz has the problem. Previous sound card (integrated) is fine. HDMI output is also fine. Tried the `tsched=0` workaround, did not work.
