Dotaz: Pulseaudio Rear Mic + Front Mic

[pepe_]

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.

v alsamixeru otestuju že rearmic funguje a snímá ale v pulse prostě ani neni vidět natož s nim pracovat.

 

Poradíte něco ?

Pulseaudio přebírá ovládací prvky z alsy, ale jen ty, kterým "rozumí". Umí různé názvy s různými rozsahy hodnot mapovat na jeden jasně daný "čudlík" s pevně daným rozsahem. Vývojáři pulseaudia aktivně spolupracují s vývojáři alsy. Každou chvíli na alsa-devel mailinglistu řeší problémy s touto standardizací, která spíš měla být součástí alsy, než až pulseaudia. Nestalo se, tak se to pulseaudio snaží napravit.

K těm mikrofonům. Dvorní specialista Canonicalu na pulseaudio poslal již do pulseaudia patch http://www.mail-archive.com/pulseaudio-discuss@mail.0pointer.de/msg07972.html , který domapovává právě Rear Mic. Patch byl akceptován, zřejmě už bude v nových distribucích, to nevím, osobně pulseaudio nepoužívám. Řekl bych, že z něj lze vyčíst, jak rozšířit konfigy pulseaudia, aby ten mikrofon taky začal nabízet. Má své ppa repozitáře https://launchpad.net/~diwic , možná bys tam aktuální pulseaudio s aplikovaným patchem pro svou verzi našel, pokud máš ubuntu.

Tak sem se mrknul na ten patch , a udělal vlastní soubor : /usr/share/pulseaudio/alsa-mixer/paths/analog-input-mic.conf.common

a po rebootu ?  Už to nabízí  Microphone1 Microphone 2 a Line in a funguje to !

 

Díky za rady.

Takže konečně spokojenost

[dustin]

Tady je pěkně vidět, co jsem psal o té standardizaci názvů ovládacích prvků. V jednom driveru máš "front mic" a "rear mic", ve druhém "mic" a "internal mic". Významově je to správně, ale pusleaudio odmítá slepě přebírat tyto názvy, protože jsou pro konečného uživatele často matoucí, a proto mapuje jenom ty základní, kde je to jasné. Pak chodí do alsy žádosti, aby se některý ovládací prvek určitého driveru přejmenoval, aby nemuseli mít tak dlouhé seznamy názvů "ekvivalentních" čudlíků pro různé zvukovky.

[pepe_]

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 ...

[dustin]

Kdyby to bylo tak jednoduché, už by to určitě dávno udělali. Zabývá se tím několik docela chytrých lidí. Ale je to open source, příležitost pro každého. Kdybys hodil svůj záměr do mailinglistu pulseaudia, určitě by ti někdo pomohl se do začátku zorientovat. Ale nemyslím si, že to bude záležitost pár grepů, aby to opravdu spolehlivě fungovalo. Už jenom proto, že se to musí přepínat dynamicky podle právě navolené zvukovky.
