How to determin if the resource is busy

[JesseGuoX]

When I use PJSIP to implement VoIP application and use 'beep' play wav file in another application, it returns 'resource busy'. Is there any function or error return to determin if the audio resource is busy.

ALSA lib ../../../alsa-lib-1.1.0/src/pcm/pcm_dmix.c:1029:(snd_pcm_dmix_open) unable to open slave
aplay: main:722: audio open error: Device or resource busy

Hi! Sorry for not responding earlier, I was taking a break.

There is currently no function in Beep or Oto for this. Have you found a solution since or is this still a problem for you?

It's still a problem. :)
