FYI, the latest version I committed right now contains the following
fixes:

- The volume scale is corrected; 100% corresponds to 0dB now
- The dB scale is also shown (in the supported mixers)
- The native timer interrupt is used for updating PCM streams on
  emu20k1 so that you get more accurate updates.  On emu20k2, still
  the system timer is used.  PA should work better now on emu20k1.
- Mixer controls have device number 0 (just internal issue)
- 64bit DMA support
- SG-buffer support
- Fix surround / rear name confusion
- Fix build on non-intel architectures
- Lots of code clean-ups
