Suono in linux, non lo sento più

[spk]

cambiando slot pci alla scheda audio mi sono ritrovato che non ho più il suono in linux

per la precisone suona sul /dev/dsp

esempio pratico: apro un film in mplayer...non sento il suono dalle casse

eseguo un cat /dev/dsp....do invio, e sento il suono (molto brutto e gracchiante)

i moduli caricati all'avvio sono quelli giusti, ed i canali dell'alsa mixer li ho già smutati tutti

MPLAYER allo start mi dice:

Building audio filter chain for 48000Hz/2ch/s16le -> 0Hz/0ch/??...
alsa-init: 1 soundcard found, using: default
alsa: 48000 Hz/2 channels/4 bpf/65536 bytes buffer/Signed 16 bit Little Endian

Building audio filter chain for 48000Hz/2ch/s16le -> 48000Hz/2ch/s16le...
Starting playback...


PS: ovviamente la scheda audio funzionava alla perfezione prima del cambio slot

hai già provato a dargli come root

alsaconf e riconfigurare la periferica e poi con alsamixer alzare i volumi (digita il tsto M sui cursori contraddistinti con mm) ??

[spk]

a dire il vero stavo cercando l'alsaconf in questo momento

ma anche un sudo find / -name alsaconf non mi trova nulla

eppure alsa-base e alsa-utils sono già installati

ah per precisione, la distribuzione in questione è una ubuntu


comunque ho già capito che questo è successo in seguito ad uno spegnimento brutale piuttosto che dal cambio dello slot

il forced check dell'hard disk ha rilevato qualche problema nella master partition...forse è saltato qualcosa

in effetti l'orologio segna le 00:30 ...

[Fil9998]

Originariamente inviato da spk

eppure alsa-base e alsa-utils sono già installati

ah ..

mmm... mmm ... butta via i files di configurazione reinstalla alsa base e alsa utils con l'opzioen "reinstalla da zero" (cioè butti via i pacchetti installati prima di installarci sopra i nuovi)

spegni e riavvii (lo so non dovrebbe servire... )
alsaconf
alsamixer come ho già detto

vedi che il server sonoro predefinito sia l'alsa e restartalo eventualmente.




di più non saprei, UN ESORCISMO o un reinstallone.

[spk]

a parte che ero in chat della community di ubuntu e mi è stato detto che alsaconf è stato eliminato da tempo e non è stato sostituito con nulla

come faccio a controllare che il server ALSA sia il server predefinito?

per l'esorcismo...se proprio insiste a non andare



EDIT: non posso fare la rimozione completa di alsa perchè mi cancella anche ubuntu-base e ubuntu-minimal....il che sarebbe alquanto grave per il sistema

ho provato il semplice reinstall,ma senza risultati

[spk]

questo è il CAT /DEV/SNDSTAT:

Sound Driver:3.8.1a-980706 (ALSA v1.0.10rc3 emulation code)
Kernel: Linux UbuTV 2.6.15-27-386 #1 PREEMPT Sat Sep 16 01:51:59 UTC 2006 i686

Synth devices: NOT ENABLED IN CONFIG

Midi devices:
0: MPU-401 MIDI 0-0

Timers:

Mixers:

la situazione non è cambiata, suono zero dalle casse se non do un cat /dev/dsp (che comunque fa sentire da schifo)

EDIT: ho fatto un controllo
/etc/init.d/alsa-utils (script di avvio del server alsa) si avvia correttamente


la scheda ed alsa figurano perfettamente installati e funzionanti, ma l'output lo posso sentire solo sul dev/dsp

ma alsa non dovrebbe usare /dev/snd/*?

HO RISOLTO!!


dopo difficili peripezie mi è stato consigliato di controllare i canali del mixer, e non solo abilitare il master ed il PCM, ma anche controllare che non ci fossero altri canali a disturbare l'output diretto

ed ecco per magia saltar fuori il canale Exchange DAC...che ancora non ho capito cosa serva, perchè mi è stata appena data la pagina del manuale per il driver alsa della mia scheda audio...ma che comunque,da abilitato, non mi faceva sentire alcun suono


PS: per chi stesse cercando l'alsaconf...è stato proprio eliminato dalla community perchè obsoleto, lo script di start del server alsa (alsa-utils) è tutto ciò che serve per far funzionare l'audio, con ovviamente i moduli caricati

ringrazio in particolare i ragazzi di #debian-it (in effetti nel mio caso mi hanno saputo consigliare più dei ragazzi ubuntu ) per avermi aiutato nell'impresa...sperando che qualche utente di hwupgrade non me ne voglia male, ma la citazione è doverosa
