What I have only just done is compile the ALSA modules from the 1.0.11-3 sources at http://www.lxtec.de/debarchiv that have had the alsa-timer-irqsave.patch applied. Even with module-assistant, it wasn't immediately straightforward to go from the alsa-source and linux-source-2.6.17 to produce modules that had a version number of 2.6.17-1-686 to match the kernel. Anyone care to write a how-to? Having done that, MIDI playback under kernel 2.6.17-1-686 with the SoundBlaster Live! 5.1 model 0220 sound card now works fine (-:. Arthur.
