[alsa-devel] Error in configuring playback device
Hello all
Problem :
1) I have an playback thread which i am closing and creating based on certain conditions Some times the my thread does not exit grace fully due to which my snd_pcm_close() does not gets executed.
2) Next time when i create thread i get error in configuring playback device
My idea to solve above problem :
Can i alwayse close the device handle before opening it if pointer to playback handle exists For eg :
if(playback_handle) snd_pcm_close(playback_handle); snd_pcm_open(playback_handle);
Please suugest me some better method to solve the problem.
Regards

This will work, as long as you ensure that playback_handle is always set to NULL when the device is actually closed.

playback_handle gets initialized to NULL. Therefore snd_pcm_close() does not gets executed in if condition My snd_pcm_open() always fails for first time even if i reset my hardware.
Please provide me some hint so that i can over come the above issue
if(playback_handle) snd_pcm_close(playback_handle); snd_pcm_open(playback_handle);
This will work, as long as you ensure that playback_handle is always set to NULL when the device is actually closed.
