[Opalvoip-user] Playback underrun error

[Venot E. <e....@vo...>]

Hello,

I'm using Opal 3.16.1 to build a Softphone Activex.
On some configuration (I think related to computer hardware running the 
softphone) there is frequently the following error :

2016/06/05 12:09:22.710    Jitter      Consecutive overflow packets, 
resynching

2016/06/05 12:09:22.717    Media       Raw channel read error: The 
previous ownership of this semaphore has ended.

After it the call is not ended but there is no more sound.
The Windows events logs give nothing at the time where the problem occur.



The problem seems relative to the headset. Do you think it can comes of 
an invalid configuration "m_soundChannelBufferTime" and or 
"m_soundChannelBuffers" on my OpalPCSSEndPoint ? Or do you think the 
problem is related to something else ?

Thanks in advance.

Regards,
