I have had many problems with my patches but this one is the weirdest and I can't seem to find the problem.
I have 3 BeagleboneBlacks in a network,all communicating to each other,sending audio using streamin~ and streamout~ with some FX. All works well for some while,but then, suddenly,for no apparent reason one of my systems makes a glitch where it seems that it reroutes the incoming signal from streamin~ which should go to DAC~ (out to the speaker) to ADC~. To simplify the patch has streamin~ connected to DAC~ (speaker) and ADC~ (microphone) connected to streamout~. But after this glitch/crash happens to signal is comming in from the actual microphone or coming out to the actual speaker, but instead the streamin~ goes directly to streamout~/ DAC~ to ADC~. It seems that it changes something with the sound card or drivers just before it happens because there can be heard some pops and clicks in the speaker for a second.
I am using PD on BeagleboneBlack, with usb sound card and OSS drivers.
Any ideas/simmilar problems?
ADC~ and DAC~ weird crash/glitch
i'm not familliar with the streamin/out object, but you could try to use the [udpsend~] and [udpreceive~] from the mrpeach externals. i use them to stream audio to my beaglebones inside my audio hardware to avoid cables that immobilize my laptop. never hd any problems with them.
Sadly the problem remains.
Any other ideas or maybe somebody has had simmilar glitch?
It really seems that pd sends input to dac~ directly as autput from adc~ after some problem with audio processing or maybe the input in mic being too loud.
What does "media" .."audio settings" tell you before and after this "crash".
You could use this.... get_audio_parameters.pd in your patch to see some of those same settings. Maybe it is the soundcard driver that is a bit flaky, although I would expect pd to "stop" if there is such a major audio problem.
