I can confirm this definitely solves the volume problem for me. I can increase the pcm and spdif volume to 100% and no clipping or distortions whatsoever happen on the spdif output. Works like a charm. So far the other distortions I wrote about are now only hearable when I turn up the volume of my headphone to nearly its maximum. If it stays that way, I can live with it... reminds me, before the problem was fixed, I had my headphone at almost 100% most of the time, so that could be the reason why those distortions where so visible in the first place. I'll have an eye on it... I am curious, will that patch make it into the offical mercurial repository and what was the problem exactly with the analog loopback? Thanks for taking the time!
