We had such a use case a while ago, where we had a source whose sample rate could change at any time, but ALSA sets up the stream configuration (sample rate etc) when the stream is opened (hw_params()) and it doesn't seem to be possible to reconfigure it on the fly. In the end we dropped the idea and solved the problem a different way. /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
