---snip--- New features: 1. Optional multichannel recording (32 channels on Live!, 64 channels on Audigy). All channels are 16bit/48000Hz/mono, format is fixed. Half of them are copied from sound output, another half can be used to record any data from DSP. What should be recorded is hardcoded in DSP code. In this version it records dummy data, but can be used to record all DSP inputs, for example.. Because there are no support of more-than-stereo sound streams multichannell stream is presented as one 32(64)*48000 Hz 16bit mono stream. Channel map: SB Live!

Do not assign negative values to variables used to index emu_cards array. This array was never accessed when index is negative, but Alexander (netchild@) told me that Coverity does not like it. After this change emu_cards[0] should never be used to identify valid sound card. 2. Fix off-by-one errors in interrupt manager. Add more checks there. 3. Fixes to sound buffering code now allows driver to use large playback buffers. 4. Fix memory allocation bug when multichannel recording is not enabled. 5. Fix interrupt timeout when recording with low bitrate (8kHz). Hardware: 1. Add one more known Audigy ZS card to list. Add two cards with PCI IDs betwen old known cards and new one. Other changes: 1. Do not use ALL CAPS in messages. Incomplete code: 1. Automute S/PDIF when S/PDIF signal is lost. Tested on i386 only, gcc 3.4.6 & gcc41/gcc42 (syntax only). ---snip--- This commits enables a little bit of debugging output when the driver is loaded as a module. I did a cross-build test for amd64. The code has some style issues, this will be addressed later. The multichannel recording part is some work in progress to allow playing around with it until the generic sound code is better able to handle multichannel streams. This is supposed to fix CID: 171187 Found by: Coverity Prevent Submitted by: Yuriy Tsibizov <Yuriy.Tsibizov@gfk.ru>
