[Tech] Problemi scheda audio trident con RH9.

[Daniele Masini]

Ho recentemente installato RedHat 9 su di un èportatile (travelmate Acer)
sul quale c'era stata installata la RedHat 8.0. Ma con l'upgrade non
funziona più la scheda audio (una trident) che prima funzionava. Ho provato
con sndconfig, ma non mi è riuscito di farla funzionare.

Di seguito riporto i dettagli del problema.

(lo stesso si ottiene con dmesg)

Qualche suggerimento?

Grazie.
