[PATCH] [2.5] maestro volume tuning

[Samuel Thibault <Samuel.Thibault@ens-lyon.fr>]

Hi,

Here is a patch which tunes the volume control of maestro sound boards:
The log conversion seems not good for PCM and CD. The volume buttons
incrementing / decrementing the main volume by 10 on 100 is too much, I'd
rather set it to 5.

Regards,
Samuel Thibault
