Well, as a special favour to Thorsten, I added the 'u' key now for the upcoming mpg123 1.26.0 to (un)mute in the audio backend, at the end of the optional buffer, so that it works immediately like pause.
This was not as easy as it sounds, as I wrote the output library without detailed knowledge of how sound is represented in the various encodings (as it should not need to know, only the audio device has to bother). I had to introduce a funky way for it to construct a stream of zeroes in signed (easy) and unsigned encodings (kindof obvious, but less easy), including the funny alaw and ulaw special cases, hopefully correctly for big- and little-endian architectures. So, Thorsten, your task now is to watch out for me finally releasing 1.26.0 some time and then bugging Debian for including the new version quickly;-) You can of course start using the daily snapshot source tarball. I mostly don't break it. I do hope to ship 1.26.0 in this quarter. It's been some years too many of it in the making. And for further requests, maintai...@mpg123.org or my personal address happily take your input. I'm not mad at people not opening sf.net bug reports. Actually, wishlist items in my mailbox are easier on the eye, buried nicely, than the list of very dated tracker items that I didn't manage to get rid of over the years;-) Alrighty then, Thomas
