Package: pulseaudio
Version: 5.0-13
Severity: normal
Dear Maintainer,
I am running Debian Jessie on a MacBook Pro Retina 13 from 2103. Audio works
fine except for microphone input, which always stays silent, regardless of mu
ting/unmuting or volume settings or fiddling with alsamixer.
The pavucontrol vumeter for Input Devices Built-in Audio Analog Stereo
Port:Internal Microphone stays in a zero state.
Alsamixer shows two Microphone capture devices (Internal Microphone and
Internal Microphone 1) while pavucontrol shows one stereo device. When I
press
space on Internal microphone 1, the input in pavucontrol appears muted. When
I unmute it, the volume meter is at 100% for a fraction of a second and then
goes down to zero. If I record directly after switching to Internal
Microphone 1, only a single plop noise is recorded and then silence. This
does not
happen for Internal Microphone where only silence is recorded.
I would expect to see a working volume meter when enabling the microphone in
pavucontrol and to have working audio recording in client tools such as audaci
ty.
Thanks for looking into this or pointing to a more appropriate bug reporting
place,
Cheers,
Lukas F. Hartmann (mntmn)
