Subject: [alsa-devel] about pop chime on pcm api
Date: Fri, 30 Aug 2019 08:31:25 +0000 [thread overview]
Message-ID: <AM6PR06MB49462A448954E689F9F87D37A7BD0@AM6PR06MB4946.eurprd06.prod.outlook.com> (raw)
Hi:
Why should I call api<snd_pcm_close()> between the interval if I want to play a wav file two times repeatly, Otherwise pop chime occurs?
Eg: (fake code as follows):
Following codes works good.
Pcm.open();//open pcm device
Pcm.play(demo.wav);//set parameter and call snd_pcm_writei() to play
Pcm.close();//close pcm device
Pcm.open();
Pcm.play(demo.wav);
Pcm.close();
But following codes works with pop chime
Pcm.open();
Pcm.play(demo.wav);
Pcm.play(demo.wav);
Pcm.close();
