Audio sporco

Fedora Linux Configurazione
#1

Ciao a tutti… ho un piccolo problema che però mi sta facendo innervosire… ho intenzione di togliere winzozz ma nn posso se nn risolvo questo problema:
ascolto Hard rock e heavy metal ed è necessaria una qualità sonora eccellente (almeno accettabile) io invece sento un audio molto sporco… ip penso che i motivi possono essere due
1: codec audio (sapreste consigliarmi dei buoni codec?)
2: driver audio (ho una creative audigy SE e ho appena aggiornato gli ALSA)
per favore aiutatemi…grazie anticipatamente.

#2

per cortesia.
non usare linguaggio sincopato ( nn, xke, cmq…)

prima di tutto il cattivo audio che lamenti è comune a tutte le sorgenti sonore ?
intendo dire sia brani musicali di formato diverso, sia filmati, sia suoni di sistema, etc …

ps. su urano ascoltiamo solo metal estremo.

#3

Innanzitutto scusa per il linguaggio sincopato (nn xkè xò…)
comunque si… il suono è sporco sempre in qualunque occasione e… soprattutto non riesco a percepire l’audio in streaming (su youtube, myspace…) avete qualche idea??
P.S. W il metal.

#4

molto bene. ci occorrono informazioni.

  1. ora posta i seguenti output da dare in terminale root:

[code]# aplay -L

lspci

alsa-info --no-upload

( rispondigli di si, poi)

cat /tmp/alsa-info.txt| head -60[/code]

  1. che macchina è ?

ps: qui vanno fortissimi System of Down - Type O Negative - Rammstein

secondo me dovrebbe essere tutto a posto.
clicca con il destro sull’icona del volume, scegli regolazioni, vai in file e prova a cambiare dispositivo, “gioca” con i volumi e con gli interruttori, soprattutto con questi.
è probabile che qualche interruttore, che non deve essere attivato, sia attivato “sporcadoti” la sorgente.
fai il tutto ascoltando qualcosa e vedi se individui il problema, perché dagli output che hai fornito sembra tutto in regola.

#11

niente da fare… ho provato tutte le combinazioni…
e poi non riesco a sentire l’audio su youtube e varie…
sicuro che non si tratti dei codec scadenti o driver scadenti??
Aiutatemi… Freddy Mercury si sta rivoltando nella tomba per quanto è brutto il suono…

#12

la questione youtube la risolvi con una semplice ricerca nel sito ( funzione cerca in home).

per l’audio ( ho una macchina con la tua stessa scheda che pilota due booster da 100 W da cui esce un sound perfetto).
prova ad installare xine:

[code]# yum install xine

yum install xine-lib-extras-nonfree[/code]

quest’ultimo comando lo devi dare con livna o rpm-fusion attivati.

prova ad ascoltare una sorgente con il motore xine.

#13

scusa l’ignoranza ma come faccio ad assicurarmi che livna o rpm-fusion siano attivati??

#14

dai il comando da root:

# yum repolist all

posta l’output

ecco a te… da ciò che vedo sembrano attivi entrambi vero??
allora perché succede questo??

[root@localhost pepponefx]# yum install xine-lib-extras-nonfree

Parsing package install arguments
Package xine-lib-extras-nonfree is obsoleted by xine-lib-extras-freeworld, trying to install xine-lib-extras-freeworld-1.1.15-4.fc9.x86_64 instead

Nothing to do

#16

ok.
ridai il comando :

# yum --disablerepo=livna install xine-lib-extras-freeworld
#17

Non è cambiato niente… stesso risultato…

#18

ciò vuol dire che hai già xine installato.
ascolta una sorgente con xine, vedi se noti variazioni nella qualità.

#19

se apro un mp3 con xine dice questo:

Service ‘phononbackends/xine.desktop’ is malformatted.

ho provato ad aprire un video con i vari player e non vedo differenze ma il suono non è male… (sarà il video??)

#20

dai gli output di:

[code]# lspci -n
