Hi everyone! OK, I solved my "plugindir/libasound_module_pcm_jack.so: no such file or directory" problem. It was a bug in alsa-lib 1.0.14, which was obviously fixed in 1.0.14a. But now I try to use my jack plugin and get a smple format problem. I start jackd like this: jackd -R -d alsa -d hw:1,0 -r 48000 -p 128 -H -M -z shaped then I start aplay (both with 44100/2ch/16bin and 48000/2ch/16bit) and get: aplay: set_params:900: Sample format non available What's wrong? I have a delta 1010LT, so a lot more channels, and jack internally uses 32bit floats, but my jack-plugin is configured for stereo and the pcm.!default wraps around it like: pcm.!default { type plug slave { pcm "jack" } } So there should be some conversions. Any ideas on this? Please?
