Hi there! I'm the developer of Pulseaudio Crossover Rack ( https://t-5.eu/hp/Software/Pulseaudio%20Crossover%20Rack/ ). During a discussion yesterday evening with an audiophile who owns a five way horn system some questions arose how pulseaudio handles the timing and sampling clocks. a) If a usb sound interface uses adaptive mode, who dictates the sampling frequency? b) If a usb sound card uses asynchronous mode it has it's own sampling clock and tells the computer to send data accordingly, how does pulseaudio handle this? What happens if two interfaces are connected and they both use asynchronous mode and the clocks differ slightly? c) If doing DSP with LADSPA plugins, who dictates the sampling clock they run at? At which points in the chain will the sampling frequency by changed and resampling occur (especially when playing material with a lower sampling rate than the sampling rate pulseaudio runs at)? What exactly does the daemon config option "avoid resampling" do in this case? Should this be set to "false" to upsample at the default sink and use the higher sampling rates throughout if default-samplerate is set to 192k f.ex.? Best regards and thanks in advance, Jürgen
