Originariamente inviato da sacarde

mi sarei aspettato:

un "Capture source" o "Capture control"

io per esempio ho un: "Input Source"



p.s.
sono uguali :

amixer -c 0 contents
e
amixer -c 1 contents

Il secondo non esiste

provato con?:

amixer cset numid=28,iface=MIXER,name='Capture Source' 4

e poi:

arecord -f cd -t wav miofileaudio.wav

[CielitoLindux]

[giacomo@Pc-Arch ~]$ amixer cset numid=28,iface=MIXER,name='Capture Source' 4
amixer: Cannot find the given element from control default

[sacarde]

bo....

ci hai provato altre distro?

[CielitoLindux]

Con questa web cam non ancora. Ci proverò debian. Ma già avevo provato con altre 2 webcam e con Fedora olter che con Arch ma stessi risultati. Niente audio. Eppure con Windows tutto funziona regolarmente.

[sacarde]

mi dici marca e modello della webcam?

[CielitoLindux]

E' questa senza cuffie però. Non ci sono driver sul sito.

[CielitoLindux]

Rettifico. E' questa. In prtica la stessa ma con microfono incorporato.

Riesumo questo post per una domanda. Piochè penso che il problema sia la scheda audio integrata avrei trovato questa. Qualcuno sa se sono supportate nativamente da Linux? O se cmq in qualche modo si possono far funzionare indipendentemente dalla scheda audio interna nn funzionante?
Grazie.

Per la cronaca: l'aggeggio funziona.
