Hello Everyone, We use the pjproject-2.3 with TI-SDK 8 we are facing the following problem: "Master/sound underflow and overflow" The above problem occurs often for pjsip call made to any SIP client, and when this problem is encountered the audio path between the two is disrupted, which fails to close the Audio device, following which no more SIP calls can be made (as we try to reopen the Audio device), unless we restart the application. The details of the setup is as below: TI-SDK-8 AM335xSDK 08.00.00.00 Linux kernel verison 3.14 Below is the PJSIP log, when the problem is encountered: Master / sound Underflow, buf_cnt=0, will generate 1 frame Master / sound Underflow, buf_cnt=0, will generate 1 frame Master / sound Underflow, buf_cnt=0, will generate 1 frame Master / sound Underflow, buf_cnt=0, will generate 1 frame Please find attached both the Success and Failure logs for your reference. In the failure scenario of Audio device closure, the below logs are observed: 19:06:19.789 pjsua_aud.c Closing sound device after idle for 1 second(s) 19:06:19.790 pjsua_aud.c .Closing TI UDA1345TS: (hw:0,0) sound playback device and TI UDA1345TS: (hw:0,0) sound capture device 19:06:21.818 pa_dev.c .Stopping stream.. And in the success scenario of Audio device closure, the below logs are observed: 19:05:07.625 pjsua_aud.c Closing sound device after idle for 1 second(s) 19:05:07.626 pjsua_aud.c .Closing TI UDA1345TS: (hw:0,0) sound playback device and TI UDA1345TS: (hw:0,0) sound capture device 19:05:07.647 pa_dev.c .Stopping stream.. 19:05:07.647 pa_dev.c .Done, status=0 19:05:07.647 pa_dev.c .Closing TI UDA1345TS: (hw:0,0): 0 underflow, 0 overflow The above scenario was tested on both PortAudio and ALSA, the result being the same. Looking forward for your replies at the earliest and many thanks in advance.
