Guten Morgen,


Der S/P-DIF Ausgang meiner Soundkarte beherscht kein Hardwaremixing (natürlich nicht).
Dies scheint immer wieder Programme vor Probleme zu stellen, die versuchen, per ALSA auf hw-Devices zuzugreifen.

Die Symptome sind dann oft wie folgt:

1. Phonon startet/VLC startet/Irgendwas anderes startet.
2. Der Ton (S/P-DIF) verstummt.
3. Ich lade snd_hda_intel neu.
4. Ton funktioniert wieder.

(Ich hoffe, Ich habe keine wichtige Information vergessen.)

Was ich jetzt bräuchte, wäre ein ALSA-Setup, das als default-Device eines mit Softwaremixing anbietet. Ziel ist:

1. Der Ton soll einen Start einer "fehlerhaften" Appplikation überleben.
2. Ich möchte Minitube ausprobieren können, das per Qt oder KDE auf Phonon zugreift.

Ich hab mal was von nem dmix-plugin für alsa gehört - obs das ist ?
 
Ich habe keine Ahnung von ALSA, aber dmix sieht schon mal nicht schlecht aus.

Weitere Informationen:

Code: 
[root@eddie etc]# aplay -D iec958:CARD=Intel,DEV=0 foo.wav 
Playing WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

Das funktioniert einwandfrei. Auch mehrmals hintereinander. Nicht aber gleichzeitig ("aplay: main:608: audio open error: Device or resource busy")
Danach funktioniert mein "normales" Setup per default-device, dass den Ton dann nach setzen von "S/PDIF" in alsamixer "irgendwie" per S/PDIF ausgibt, nicht mehr. (Oben genannte Symptome)

------

Code: 
aplay -D hw:0,1 foo.wav
funktioniert auch.

Ich habe mir dann das hier zusammengebastelt:
Code: 
pcm.dmix_test {
        type dmix
        ipc_key 321456  # any unique value
        ipc_key_add_uid true
        slave {
                pcm "hw:0,1"
                format S16_LE
                rate 44100
        }
}

Die Config habe ich größtenteils von http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html kopiert.
Das erlaubt nun gleichzeitiges Abspielen mit zwei aplay's. (huhu deki)
Ich werde nun testen, ob ich die rate und format-Werte noch ändern kann, je nachdem, was mein Receiver unterstützt.
Danach werde ich gucken, was denn wohl Phonon (erschauder) zu dem dmix-device sagt.

----------
Code: 
[root@eddie asound]# aplay -D dmix_test foo.wav
Playing WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
underrun!!! (at least -1260467843931.547 ms long)
underrun!!! (at least -1260467843931.548 ms long)
Die beiden Fehlermeldungen erschienen kurz vor Ende der Datei, aber noch zu früh, um dadurch ausgelöst worden zu können. Das hängt doch sicher mit den rate/format-Einstellungen zusammen?


MfG, PyroPeter

EDIT:

Neue asound.conf:

Code: 
pcm.!default dmix_plug
ctl.!default dmix_plug

pcm.dmix_test {
        type dmix
        ipc_key 321456  # any unique value
        ipc_key_add_uid true
        slave {
                pcm "hw:0,1"
                format S16_LE
                #rate 44100
		rate 48000
        }
}

pcm.dmix_plug {
	type plug
	slave.pcm "dmix_asym"
	hint {
		show on
		description "S/PDIF out + dmix + asym + plug"
	}
}

ctl.dmix_plug {
	#type hw
	#card "Intel"
	type shm
}

pcm.dmix_asym {
	type asym
	playback.pcm "dmix_test"
	capture.pcm "fake_capture"
}

pcm.fake_capture {
	type null
}

Nun habe ich ein ganz tolles Problem:
Mehrere aplays laufen, nur xmms2+aplay oder phonon+aplay funktionieren nicht.
Code: 
[root@eddie asound]# aplay -D dmix_plug foo.wav 
ALSA lib pcm_dmix.c:1010:(snd_pcm_dmix_open) unable to open slave
aplay: main:608: audio open error: Device or resource busy

Mein (teilbelegter) Verdacht ist, dass xmms2 und phonon auf das mixer-device zugreifen (ctl.dmix_plug) und dieses nicht simultan von mehreren Prozessen benutzt werden kann.

Ich bin ja mal gespannt, ob ich es jemals schaffen werde, ein einigermaßen funktionierendes Sound-Setup zu finden.
