[alsa-devel] ALSA Control Interface - default values?
Hello,
when writing an alsa driver, in the info callback of the control I can specify which range of values this control does accept (uinfo->value.integer.min and .max). If I put 1 as minimum and 10 as maximum for example, I would expect that the default value of this control is something in between the range, e.g. 1, after the driver is loaded.
But I figured out, that ALSA initializes the control with a value of 0, which is not in between the range.
Can someone please tell me why ALSA initializes the Control with a value of zero, even if the minimum in the info callback is 1 ?
Is there any way to initialize the control with some "default" values, aside of snd_ctl_add()?
Best regards and thanks for your help! Max

What is the problem here? The driver is responsible for the default values - where do you believe that ALSA is overwriting the values you're looking for?
