Capture only, playback only ou "capture & playback"

eleandar utilisateur non connecté France
Salut,

Est-ce qu'il existe une ligne de commande permettant de déterminer si mes cartes son sont capture only, playback only ou les deux ?

Peut-être en utilisant pulseaudio ou alsa ? J'ai trouvé pacmd mais je n'arrive pas à faire le tri dans les informations affichées pour savoir à coup sûr et sur mes différentes cartes son leur caractéristiques !

Voilà les résultats que j'aimerai retrouvé:
C-Média USB : Capture Only / Câble Jack vers Usb
HDA Intel : Les deux / Carte son interne PCI
USB Audio Codec : Les deux / Carte externe Berhinger UCA202
HX Stomp : Les deux / PedalBoard HXStomp Line6

Merci d'avance,
Laurent

Il semble que le driver alsa crée une sortie stéréo pour la carte C-Media ... J'imagine que c'est pour monitorer le signal mono ...

Ça marche très bien dans Jack ... Je branche la C-Media et j'écoute ce qui est capturé par la C-Media sur la HDA Intel.

Est-ce que la mention mono-fallback serait d'une utilité pour savoir si c'est capture only ?

Avec cette ligne de commande, on y voit mieux (tout du moins j'espère):
