ice1724 - Changing Level Meters from MIXER to PCM?

[Pavel Hofman <pavel.hofman@xxxxxxxxxxx>]

Hi,

Following your discussion on moving low-level controls from MIXER to PCM
types, I would like to suggest the following two patches:

diff --git a/sound/pci/ice1712/ice1724.c b/sound/pci/ice1712/ice1724.c
index 3896fb9..28ca8a4 100644

        .name = "Multi Track Peak",

+       snd_ctl_elem_value_set_interface(peaks, SND_CTL_ELEM_IFACE_PCM);
        snd_ctl_elem_value_set_name(peaks, "Multi Track Peak");
 }




The point is these controls are read-only, display incorrectly in
alsamixer, and are very confusing for majority of users who do not read
envy24 datasheet and the source code.

Thanks for considering this IMO useful change.

Regards,


Pavel.
