The SBLive is a rather complex chip for a sound chip, with a lot of digital signal processing capability. Apparently, the ALSA driver, by default, provides some programming for the DSP, and exposes this through the mixer. Hence, a rather complex mixer. IEC958 appears to be the standard behind S/PDIF, the Sony/Philips Digital Interface Format, which is what is normally used for digital output. Given that, a number of sliders names become clearer. More information can be found in the Linux source tree (or, if you have kernel-doc installed, under /usr/share/doc/kernel-doc-2.6.10) at Documentation/sound/alsa/SB-Live-mixer.txt or on the Web at http://lwn.net/Articles/64341/ Hope this helps, James. -- E-mail address: james | History books in Ireland and Scotland are littered @westexe.demon.co.uk | with the 'wrong' spelling, and there is no law that | tells you how to spell whisky.
