I have some preliminary results. The driver on the Touch released firmware works great. No ticks, pops etc. I tested this by putting some wav files on an SD card and used aplay to play them. It was perfect. The async behavior worked correctly.
BUT when playing from squeezeplay (the Touch player software) I get the ticks and pops as others have described. So at least I can duplicate the problem. An adaptive USB device works much better, but still occasionally has ticks and pops (primarily at the infamous 10 secs before end of track). One possibility is that the USB driver uses more cpu resources than the I2S and S/PDIF drivers, so I tried doing things that use more or less cpu and got no difference. I tried running off TinySBS rather than the network and still got exactly the same results. So it doesn't look like its a generic "cpu load" or network issue. I then loaded Soundcheck's 2.0 mods to try the buffer size change and got no sound at all. Aplay could still play, but when the ALSA config had squeezeplay pointing at the Streamer, nothing, no matter what the buffer setting. The digital and analog outs still work great with the 2.0 mods in place, its something that just affects the USB driver. Next I'm going to spend some time looking into what the mods do that stops it all together and see if that leads to finding out what the problem is.
