When any streaming video is played the sound on the Laptop Speakers stops after a few seconds, the length of time varies. The video image is still playing, only the sound stops. This happens on both Youtube (using HTML5) and Netflix (using Silverlight).
The speaker volume is still on, and Youtube and Netflix do not show as muted. The Sound Mixer shows activity for the audio stream but no sound is coming from the speakers. If I plug in the headphones there is sound. When I unplug the headphones there is sound again from the laptop speakers but after a few seconds the sound from the laptop speakers quits again. Each time if I plugin then unplug the headphones the laptop speakers seem to wakeup and the sound starts again for a few seconds then quits again. Also, if I Pause the video and press Play again the sound also restarts on the Laptop Speakers (this happend in both Youtube and Netflix).
It is happening in all of the internet browsers I use. The following is the information on the laptop and programs.
Chrome Version 42.0.2311.135
Internet Exployer Version 11.0.9600.17728
Toshiba Sattelite L750 Laptop, Windows 7
Laptop Speakers = Conexant Smartaudio HD, driver = 126.96.36.199
Microsoft Silverlight (64-bit) Version: 5.1.30514.0
Flash Player Version 188.8.131.52
I have run the Flash Uninstaller and reintalled Flash Player but the same thing happens.
I have also tried running Firefox in Safemode and the same thing happens
I have also reloade the drivers for the Conexant Smartaudio HD
Any assistance would be greatly appreciated.
