Yes SOUND_MIXER_VOLUME is supported and would work also - but up to the
limit set by the gain. The DaVinci OSS driver uses the V3 of the OSS
API. There are some pointers as to which mixer ioctl to use depending on
what you want to do at http://www.4front-tech.com/pguide/

Then what is SOUND_MIXER_WRITE_VOLUME ? I can control
the volume using this ioctl also. How does it differ
from SOUND_MIXER_WRITE_OGAIN ?
