Yes, I've been missing your regular contributions in the past months ;) Basically: the decoder thread feeds music_chunk objects into a music_pipe. The player thread takes them from there, and appends them to the output's music_pipe instance. The output threads now consume them. When all output threads have consumed a music_chunk, it is freed (returned to the music_buffer). The frequent wakeups (supposedly) come from the threads waiting for more chunks, or waiting for enough room in the pipe, or waiting for free chunks in the music_buffer. They're just using g_usleep(10ms) to synchronize, because I havn't had time to think about the proper solution yet (using GCond or struct notify). For most setups (small buffers, low latency), the music_pipe/chunk/buffer code is more efficient than the old method (fully synchronous buffer passing), but for your setup, it's worse. We will optimize MPD for all possible use cases. I believe it'll take some time to fully understand that code, so if you have little time, I promise to fix it this week.
