As I am not sure at this venture, whether my issue is software/hardware, I opted to post in this section.
Basically, it's an audio issue with my wife's laptop, where the audio randomly drops around 2-4 minutes of playback.
Now, after extensive "check this/check that" ... "deactive/re-active" etc. and fully re-installing the Realtek Audio Manager/Drivers, I am no further forward.
Here is what I do know, the system appears to think that nothing is wrong, everything at Windows 10 "user level" reports that all is operating normal, no yellow question marks, no greyed out sound settings etc. etc.
Oh yes, and when the sound output drops, plugging in headphones still delivers sound. Only the laptop speakers lose sound, until rebooted.
If anyone had experienced a similar scenario ... I would love to hear from you.
All the best,
