A few months ago, Clemens was kind enough to explain how to set a volume control, given its name, using the snd_ctl_elem_value_xxx functions. By experimenting on my Ubuntu system, it appeared that values from 0 to 0xFFFF ran the master volume through its entire range, as shown by having alsamixer running at the same time.
Now, I run the same code on an embedded board, and it's always maxed out, or off at the bottom. I used "alsactl store" on both systems, and the master volume entries on both systems are identical, specifying a range of '0 - 64', a dbmin of -6400 and a dbmax of 0. (I assume those are really millibels.) So how does one programmatically find the range of a control? I'd prefer to have plain linear voltage control, but I'll take anything I can get as long as I know what the shape of the curve is. -- Ciao, Paul D.
