Servus,

folgendes Problem:
Meine Boxen sind stumm beim Abspielen diverser Audio-Files/Streams/Videos (und ich finde/bekomme keinen Fehler). Da ich ein Dual-Boot System habe kann ich sagen unter Windows funzt alles soweit, sprichen Boxen sind korrekt angeschlossen... Alsa-Howto bin ich x-mal durchgegangen

Soundkarte: Audigy LS

Kernel: 2.6.9-r13
Flags bzgl. Alsa:
* Sound Card Support
* ALSA
M Sequencer Support
M Sequencer Dummy Support
M OSS Mixer API
M OSS PCM
--> PCI Devices
M Emu10K1


Code:
/etc/init.d/alsasound start
 * Loading ALSA modules...
 *   Loading: snd-card-0...                                               [ ok ]

Vielleicht hast du vergessen die Karte zu unmute. Schau hier http://www.gentoo.org/doc/en/alsa-guide.xml wie man das macht

Code Listing 3.5: Running amixer

# amixer

If amixer produces lots of output then you're ready to unmute the channels. If you receive an error, doublecheck that your soundcard module is started.

Now unmute the Master and PCM channels. If this isn't sufficient, also unmute the Center and Surround channels.


....

gemacht, leider ohne Erfolg...

Hast Du mal mit nem anderen Player versucht, was abzuspielen? Ixh finde xmms ist sehr sparsam in seinen Fehlermeldungen. Möglicherweise gibt 'mplayer -v song.mp3' mehr Auskunft über den Fehler

Dann hab ichs abgebrochen... Ich habe gestern Alsa nochmal komplett neu installiert nach dem www.gentoo-wiki.com Guide, leider wieder erfolglos.
Ich wuerde ja langsam aufgeben wenn ich nicht wuesste das es unter Windows funktioniert UND auch schonmal unter Gentoo funktioniert hat.

Da ich damals den genkernel hatte habe ich ihn heute inkl. Coldplug zusaetzlich installiert, aber selbst dort funktioniert der Sound-Output nicht mehr. Wenn ich wenigstens irgendwo einen Fehler bekommen wuerde :cry:

Tja.. Hast Du schon mal versucht mit emu-dspmgr die soundroute manuell zu setzen?
Sonst wüsste ich auch nix weiter :-(

Hast du mal einfach mit dem amixer ALLE channels auf 100% gesetzt? Hast du USB-Soundgeräte angeschlossen, so daß deine Karte vielleicht nicht die erste sondern die zweite ist?

manche karten haben mixer-geräte die zusätzlich aktiviert werden müssen.
bei meiner (VIA8235/VIA1612A) sind das zusätzliche 4 VIA-DXS-Kanäle ganz rechts im alsamixer.

Hast du versucht, in "alsamixer" die 4 "Analog" Kanäle zu unmuten?. Meine Audigy LS hat keinen zentralen PCM- oder MASTER-Regler.

Dumm, dass ich die Karte schon ne Weile hab. Umtauschen ist da nicht mehr, was ich sicher getan hätte, wenn ich von ihren Quärelen im Umgang mit Linux gewusst hätte [5.1 Sound kann man gleich vergessen, bloss Stereo (Front Speaker + Subwoofer) ist möglich. Ich hoffe das kommt noch in zukünftigen ALSA Versionen] :roll: .

Hä? Die Audigy LS läuft mit dem Emu10k1 Modul? Seit wann denn dass?
