答复: About Sound Card(ak4613) Periodic sounds pause (about 80s)

HI ,

I’m sorry, it’s a mistake in my work.

 

The runtime version is AGL Eel 5.1.0.

 

The Testing Process:

I started M3 and another development board and configured IP of the same network segment.

IP address of M3 was 192.168.3.101, and IP address of another development board was 192.168.3.100.

Run gstreamer's send command on another development board:

gst-launch-1.0 audiotestsrc freq=400!Audio /x-raw, format=S16LE, rate=48000, channels=2!Audioconvert!RtpL24pay!Udpsink host=192.168.3.101 port=10003 sync= true-v buffer-size=1000000 qos-dscp=56.

Run the receiving command of gstreamer on M3:

gst-launch -1.0 udpsrc port=10003 caps="application/x-rtp, media=(string)audio, oo-rate =(int)48000, encoding-name=(string)L24, encoding-params=(string)2, channels=(int)2, payload=(int)96,SSRC = (uint) 359808935, timestamp - offset = (uint) 294838934, seqnum - offset = (uint) 31389! ""Rtpjitterbuffer latency = 300!RtpL24depay!Audioconvert!Alsasink sync = true device = hw: 1, 0

 

       When I used dab4.0.2, I needed to use alsamixer to adjust the volume of ak4613 (since it started at 0), but now Eel's version 5.1.0 doesn't need it because the initial volume is just right

       I listened to the sound received by the M3 side through the headset, and found that every 1min20s, there was a brief pause, and when other operations such as SSH connection also caused the same brief pause, the last brief pause cycle would start from this time, As in the following example :

       0      ->  1min 20s       -> 2min 40s        -> 3min                                    -> 4min 20s           ...

       Start -> voice pause    -> voice pause     -> SSH resolved voice pause      -> next voice pause    ...

Best regards

Hi ,

Thanks for reporting that issue.

However, could you please be more specific about your setup ?

- What is your runtime version ? Is it Eel or Flounder ?

- What is the 4A audio role you use, if any ?

- What is your gstreamer command line please ?

Thanks for providing us with these additionnal information

Best regards

HI all:

       When I test the gstreamer through M3（AGL）,  M3 is the receiving end of gstreamer, M3 is the receiving end of gstreamer（udpsink）,  and another development board serves as the sending end of gstreamer(udpsrc).

       Start -> voice pause    -> voice pause     -> SSH resolved voice pause      -> next voice pause    ...

 

phenomenon :

The sound that the M3 plays does not last, and there is always a periodic brief pause

 

Anybody ever had this problem? Can you help me.

 

Best wishes to you.
