Now I'm starting with pulseaudio --start. It works, but after stopping the execution of a song. The source goes away and I need to re-pair again the client. I attach here the daemon.conf and default.conf. Would you please check if there is something other wrong? I'm not sure about the first parameters for my setup. > > The other tunable is the resampler.

Yes, speex was compiled with --enable-fixed-point Thank you for the support Marco -------------- next part -------------- #!/usr/bin/pulseaudio -nF # # This file is part of PulseAudio. # # PulseAudio is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # PulseAudio is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
