Now i can start looking for a backend which can handle 100k of audio files without hardlocking my machine. (xbmc would be quite nice but it's frying the video card even when idle and minimzed Everything either sounds bad or has some other showstopper. After trying nearly all available media players i'm using smplayer. which also fixed these libcanberra zombie pulse clientsįinally this little option did it. and it's finally compiled to not dirty libs. (Note that the "unstable, alpha and using at your own risk" pulse is actually quite stable. Several pulse/alsa issues have been fixed and after getting rid of all the useless audio plugin/plugout stuff i managed to get a nearly enjoyable sound output. It's doing quite well for some weeks now. (letting the onboard card doing the pulse stuff and spdiffing into the audigy (because of certain alsa imitations))Īfter much more wasted time finding workarounds for several annoying bugs/regressions in 10.4 i ended up with the 10.10 alpha. The only way having sound output without getting ear cancer was to plug in my old audigy card and alsa a the "sound server". You saved me from setting up a xp machine to do audio.īeing used to SB X-Fi with foobar and its matrix mixer, everything else sounds like crap.Īudio in Linux in chaos. But that another story)Īfter many weeks of (half) wasted time and frustration i stumbled across this thread. Whithout a recent os backup i tried a quite few distros and ended up using the 10.10alpha. I just recently have converted to ubuntu because my desktop xp machine crashed. This is not simple upmixing, it is full-on surround sound decoding. So if you wanted a delay of 20ms you would use '-af surround=20' instead. It activates the surround decoder and sets the delay for the rear channels in ms.

The accepted format is currently only S16. The center and LFE channels are the average of sum of left and right Option is useful if the slave PCM has no strict input condition (like Or 6 channels appropriately suitable for the slave pcm. The channel option specifies the number of channels of output. For example, to set 10ms delay in the above case: The delay size can be specified by "delay" PCM The upmix plugin copies left and right channels to rear left and right You can use this PCM as a default one by defining below: For example, theįollowing PCM defines upmixing to 5.1 from 1-6 channels input: The number of channels to be expanded is determinedīy the slave PCM or explicitly via channel option. The upmix plugin is an easy-to-use plugin for upmixing to 4 orĦ-channel stream. If you do the nf way you send it to the device you created instead of the Alsa default. In those cases you now need to do the upmixing with LADSPA plugins for effects, or it appears you can pass that "switch" you found for surround. The thing is, if the track is stereo, it only goes to the front left and right speakers even with the -channels telling it there is more speakers available. So for a 5.1 setup where each speaker physically connects into the sound card I send -channels 6. Without the switch, Mplayer will only send out a stereo track nothing more. The -channels switch actually is to tell MPlayer how many speakers are available, and if a 5.1 audio track it should mux in the other tracks like center and LFE. They killed the quality purchased with buying Cambridge Soundworks. Sound so much better then what SB puts out now. They are the best sounding 2.1 speakers I have ever had too. One being an original Cambridge Soundworks set after the buyout before the name change. I have a couple of SB 2.1 systems like that. The signal sent to each is a full range signal with the internal high and low pass filtering handled in the speakers. You actually have a 4.0 system I am assuming that each 2.1 speaker system has only one connection to the sound card. Knowing how much they cram into MPlayer, I would not be surprised about a surround feature built into it that does effects processing on it to provide more then just fill on the other channels, like upmixing alone does. I guess using the “-channels 4” switch with mplayer will downmix the center & LFE channels in case I play a DVD with 6 channel (Dolby Digital) recording. So, technically I have created a quadraphonic speaker setup. The RR & RL channels are connected to my Sony audio system. My speaker setup is like this - A Creative 2.1 outputs the FR & FL.
