Kann PCM Capture nicht austellen

[Annaeus]

Hallo,

ich verwende Kubuntu und habe mein Telefonpartner hat bei SKype/Voip immer sein Echo, dass zu ihm zurückkommt.

Das kommt da mein Capturechannel nicht nur Mic aufnimmt sondern auch PCM, allerdings kann ich das unter Alsamixer nicht abstellen, da es dort diesen Channel nicht gibt.

Auch ein: "amixer sset PCM capture off " nutzt nichts.

Gibt es die Möglichkeit das ganze eventuell über Dmix zu unterbinden?
Oder auch irgendwo anders. Das ganze treibt mich allmählich in den Wahnsinn ^^.

Danke

Hi!

Schau doch einfach mal mit alsamixer nach, welche Kanäle bei dir überhaupt fürs Capturen vorhanden sind. Achte vor allem auf "Analog Mix" o.ä.

hi. Ich habe Line, CD, Mic, video, Phone,Aux,Capture, Mix und Mix Mono.

Mic wird "gecaptured" ,Capture selbst im Moment nicht und die Lautstärke ist auf 0. Skype ging trotzdem, aber nur mit starkem Echo.

Genaugenommen sieht es so aus:

Der amixer Output könnte vielleicht auch noch interessant sein

Äh, dann komme ich zu dem oben geposteten Screen und dann?

Spiele gerade mit alsactl rum.
Kann man vielleicht hier etwas frickeln, damit es geht?

Es ist ja kaum vorstellbar, dass Linux dazu einfach nicht in der Lage ist.
Unter Windows funktioniert es einwandfrei.
Konnte allerdings auch in der Alsa-Mailingliste nichts dazu finden, obwohl das Problem auch shcon von mehreren bei Skype.com und in den Gentooforen beschrieben wurde.

Könnte es am Treibermodul liegen?
Ist hier jemand der VoIP ohne Echo mit i8x0 hinbekommen hat?
