Re: [alsa-devel] On mixer controls naming

The other control I've named "Tone Control - Bass", as indicated in writing-an-alsa-driver.pdf. But alsamixer shows it under both "Playback" and "Capture" views.

How can I restrict this latter control to just playback?

For a control to be classified as a playback control, its name must have one of the suffixes " Playback Enum", " Playback Switch", " Playback Route", or " Playback Volume".
