It was bug #21. These click and pop problems were actually much earlier, so possibly that was before the bug system was put in place. I do remember that I, and others, were asking for a bug reporting system to be put in place and it eventually was. In response to the problems I and others were having with the HDSP 9652 I gave Thomas Charbonnel log in rights, as well as root password, and he was doing development and debug on my machine at that time. He was the main developer on the HDSP drivers at that time but actually didn't have the HDSP 9652 to work with directly. He made changes looking at this and other problems. I viewed the output of hdspconf and hdspmixer to see the resutls and report back. It was a very intereactive process that produced some good results - hdspmixer working far better and more compatibly with the RME versions. Fially, as I stated earlier, I think this problem was specific to the use of the AI-3 since it ran at 48K. This may or may not be true, but it was my thought at the time. I did find a few notes in Google. Read them if you're interested. http://www.mail-archive.com/alsa-devel@xxxxxxxxxxxxxxxxxxxxx/msg10338.html http://lists.tartarus.org/pipermail/alsaplayer-devel/2003-December/001626.html Cheers, Mark
