[Risolto] Assenza audio con Sch. Video DVI su Monitor HDMI

[gianbru73]

Salve a tutti, ho da poco installato ubuntu 14.04.2 LTS; ho collegato il PC ( l'uscita DVI della scheda video) al monitor (ingresso HDMI), per quanto riguarda il video sembra tutto ok ma non ho nessun audio (premetto che ho in dual-boot windows 7 e tutto funziona).
Al terminale ho dato il comando

Codice: Seleziona tutto

lspci -v

, di seguito il risultato:

Oltre ad una scheda PCI-express Asus GeForce 7300GT con uscita S-VGA e DVI ho una scheda video integrata GeForce 8200. Ho cercato di installare i driver proprietari NVIDIA ma mi da un messaggio di errore che dice che i driver non sono compatibili.
Qualcuno può aiutarmi a risolvere questo problema?
Grazie.

credo che dovresti andare in "Driver Aggiuntivi" e dovresti trovare una voe del tipo:

Codice: Seleziona tutto

Nvidia binary driver version 331.113 da Nvidia-331 (proprietario testato)

Flaggala e riavvia...... e vedi.

[Roberto Pontecorvi]

Da terminale dai il comando:

Codice: Seleziona tutto

alsamixer

poi premi F6 e controlla che le uscite s/pdif siano poste a "00" e non "MM". Se sono "MM" vai sopra con i tasti freccia (sinistro o destro) e premi il tasto "m" della tastiera.

[gianliuc]

Driver aggiuntiv stà nel pannello controlli se ben ricordo.....

Comunque ho guardato le caratteristiche della scheda video sul sito della Nvidia, credo proprio non sia abilitata ad audio via DVI, quindi penso aver risolto il problema. Grazie a tutti.

[Roberto Pontecorvi]

Non sono sicuro di quello che dici. Se la scheda ha una uscita hdmi/dvi ha per forza l'uscita audio. Tali uscite sono fatte apposta per portare tutti i segnali disponibili al monitor.

Driver aggiuntivi di configurazione dice niente?
