Hi!
After I finally switched from that CMI3738 card to Intel HD Audio (aSigmaTel chip) I have another quite interesting problem:
As the bass of the Intel HDA is a bit weak, I tried applying a LADSPAequalizer filter on it. After I spent most of the day to get thatworking I now have a problem:
When playing a wave file (stereo) with aplay --> equalizer worksabsolutely fine.
When playing a movie with 5.1 sound using mplayer --> sound iscrackling, like it can't be played fast enough, or like when you ffwdthrough a dvd. Something like that.
When playing the mentioned wave file with mplayer --> equalizer worksfine.
Is this ALSA's way to tell me that using that equalizer is not a goodidea, or am I doing something wrong?
My asound.conf looks like this:----pcm.ladspa { type ladspa slave.pcm "plughw:0,0"; path "/usr/lib/ladspa"; channels 6 plugins [ { label dj_eq id 1901 filename "/usr/lib/ladspa/dj_eq_1901.so" input { controls [ 0 0 0 ] } } ]}
pcm.!default { type plug slave.pcm "ladspa";}
pcm.!surround51 { type plug slave.pcm "ladspa";}----
The same thing happens when I use another plugin out of Steve Hariss'collection (tried with vynil).My worst fear is, that I have done nothing wrong and these plug-ins aresimply not capable of coping with multichannel audio. But why are theadditional 4 channels not just discarded, but the sound completelydistorted?
Thanks in advance for any help,Best wishes and a merry christmas to you all!Sebastian Schäfer
