Hallo zusammen,
ich bekomme an meinem Rechner den Ton über "analog Audio" nur noch mono abgepielt. Die gleiche onboard-Karte macht über HDMI-Ausgang aber Stereo-Ton.
Über amixer bekomme ich:
Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'IEC958',1 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'IEC958',2 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'IEC958',3 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'IEC958',4 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on]
unter den 'Shell-Einstellungen' finde ich unter [Klang] keine Möglichkeit den zweiten Kanal zu aktivieren, der Line-Ausgang wird ja auch als Stereo angezeigt...
mit 'aslamixer' habe ich auch keine falschen Einstellungen finde können.
