Zdravim , již na spoustě PC sem narazil na problém s Pulseaudio .
V Alse je vše ok , ta vidí a ovládá oba vstupy mikrofonu.
Pokud ale jede Pulse , dá volbu jen mikrofon a line-in
když dam : amixer cset iface=MIXER,name='Input Source'
numid=24,iface=MIXER,name='Input Source'
; type=ENUMERATED,access=rw------,values=1,items=3
; Item #0 'Rear Mic'
; Item #1 'Front Mic'
; Item #2 'Line'
: values=0
vidim že jsou vidět oba ale Pulse odmítá nabídnout vše.
Několik let , zkoušel sem na ubuntu 9.04 9.10 10.4 10.10 11.04 a stále přetrvává totéž.
u ostatních dister je to tentýž problém.
No je to normální ?
80% všech pc co mi přišlo pod rukou a mělo více než 1 mikrofonní vstup to dělá a nikdo to neřeší.
Nic pořádného na to neni.

Takže konečně spokojenost
No a proč Pulse teda při instalaci nespustí : amixer -c0 cset iface=MIXER,name='Input Source' | grep Mic
a podle výsledku neupraví /usr/share/pulseaudio/alsa-mixer/paths/analog-input-mic.conf.common
nebo že někdo na to neudělá nějakej autodetekční script. To je mizérie ...
