linux - Python alsaaudio and pjsip conflict -


i writing app in python uses pocketsphinx , pjsip use pocketsphinx keyword search wakeup app , pjsip phone problem when try call "call" function , after returning listen keyword , error message pjsip cannot open sound device:

pjsua_aud.c  ..opening sound device (speaker + mic) pcm@16000/1/20ms alsa_dev.c  ...alsa lib pcm_hw.c:1557:(snd_pcm_hw_open) open '/dev/snd/pcmc0d0c' failed (-16): device or resource busy pjsua_aud.c  ..unable open sound device: unknown error audio driver (pjmedia_eaud_syserr) [status=420002] operation=make_call(), error=unknown error audio driver (pjmedia_eaud_syserr)

this error happens when try return keyword function uses alsaaudio

so question how can open same audio device pjsip , alsaaudio?

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
