Re: New codec for STAC9766 used on Efika

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



With this version, why are these errors generated?

ALSA sound/core/control.c:334: control 2:0:0:All Analog PCM Switch:0
is already present
asoc: failed to add dapm kcontrol All Analog PCM Switch
ALSA sound/core/control.c:334: control 2:0:0:Mixer PC Beep Switch:0 is
already present
asoc: failed to add dapm kcontrol Mixer PC Beep Switch

Or is the right question, why didn't "Mixer AUX Switch" cause an error?
