debian wheezy: errore server sonoro

[magnet_80]

ho un problema:
quando mi loggo, da root, in kde, mi compare l'errore allegato qui sotto:
http://www.freeimagehosting.net/newuploads/l5iaa.png

inoltre, vi allego anche il messaggio di errore del demone kde:

altra cosa: quando entro in root, oltre al messaggi di errore del file png, il suono di ingresso viene distorto.

se entro come utente normale, tutti questi problemi non ci sono.

grazie

[magnet_80]

up.
grazie

[sacarde]

quel messaggio me lo dava anche a me per il mio utente

ho risposto in modo diverso....e .....senza capire perche'... non me lo da piu'

[magnet_80]

premetto che l'immagine hostata si vede pessima. stasera la metto da un'altra parte

cos'è che hai risposto?
è un errore mongolo, perchè:
stavo usando il pc e, da inizio giugno, in concomitanza con una patch del kernel 3.2 ha iniziato a comparire quell'errore. ho pensato che avessero variato qualcosa nel kernel. mortacci loro!!!
vabbè, rifacciamo il pc partendo da un'immagine di gennaio. aggiornato tutto, messo i firmaware non free e tutto funzionava: nessuna finestra di errore è comparsa. ho usato un pò il pc e poi ho deciso di fare l'immagine.
così ho ripreso l'immagine di gennaio, upgradato tutto e sta maledetta finestra è ricomparsa
siceramente ho pensato che poteva essere un qualcosa che fosse variato nel kernel, poi vedendo che la fisentra "vuoi che kde ignori..." elenca addirittura la scheda Nvidia ho pensato che ci fosse qualcosa sui driver nvidia nuovi che gli dava fastidio.

da root: dalla finestra "vuoi che kde ignori..." clicco su "gestisci dispositivi" e gli ho selezionato di usare l'audio analogico anzichè quello in HD.
riavvio entro come root e continua a ricomparire. mistero.

stasera faccio altre prove e poi le riposto.

[magnet_80]

adesso da root funziona tutto....
mistero!
