241 Left and right-ear volumes.
242 Although the OSS API stores volumes in integers from 0-100, \
243 we normalize them to 32-bit floating point numbers.
248 Number of user-defined mixer controls associated with the device.
250 A tail queue containing user-defined mixer controls.
252 .Ss User-defined mixer controls
253 Each mixer device can have user-defined controls.
