Allow mixer controls to be accessed through the name, not only by id.
|
|
This allows stereo controls to be set with different
values for left and right.
|
|
Just like the pcm_get_error() API, simplify the mixer API
functions to return pointers to constant strings instead
of making copies of strings.
|
|
Command-line arguments are added for:
tinyplay and tinycap:
-D n -- card number
-p n -- period size
-n n -- number of periods per buffer
tinymix:
-D n -- card number

Use existing routines to read BYTE controls. Somewhat inefficient
since an ioctl is done for every byte, some caching in intermediate
fields would be beneficial.

Otherwise we just list a device with zero controls which isn't the most
obvious failure mode.
