Hi Takashi, Hi alsa-devel.

in my last mail I had supposed scaling issues with mixer.c, but finally it turns out that was just a debugging problem of myself. I was struggled how types are handled in the code. I have some ideas for improvement but I am not sure if it its worth the work since nothing is broken.

1. get rid of convert_bytes_value(cval, value_set): This function return any type in a integer container, which is confusing.

2. use type casts in convert_signed_value(): gcc knows perfecly how to convert types.

3. merge convert_signed_value() and snd_usb_combine_bytes() to get rid of the intermediate integer variant.

I am currently working on a patch that introduces a get_ctl_value_range_v2. I want to get rid of the three single queries for min max and rate. Also here, nothing broken. Is it worth to do the work?

Kind regards

Daniel
