se eseguo il test dell'audio
$ speaker-test -Dplug:surround51 -c6 -l1 -twav

La periferica di riproduzione è plug:surround51
I parametri dello stream sono 48000Hz, S16_LE, 6 canali

Frequenza impostata a 48000Hz (richiesti 48000Hz)
La dimensione del buffer va da 96 a 87381
La durata del periodo va da 48 a 43690
Usare la dimensione massima di buffer 87380
Fasi = 4

va tutto alla perfezione si sentono tutte invece ora che ho messo in
blacklist snd_hda_intel che sarebbe la scheda audio interna e modificato
/etc/asound...
totem e rhyt.... nn mi si sentono più...
nn capisco perkè
grazie anticipate per l'aiuto
