Hello,
I used to have surround profiles, but now they have disappeared from the list. It seems this happened after a system update.
Alsa reports the surround capabilities as shown by these commands. Note howerver that speaker-test fails with 6-channel test:
Thanks
mrechte@linux2 ~]$ speaker-test -D surround51 -c 6
speaker-test 1.0.28
Le périphérique de lecture est surround51
Les paramètres du flux sont 48000Hz, S16_LE, 6 canaux
Utilisation de 16 octaves de 'pink noise'
Le nombre (6) de canaux est indisponible à la lecture: Argument invalide
Échec de la configuration des paramètres matériel: Argument invalide
