Hello everybody, I recently installed Ubuntu 14.10 dual boot on my existing Windows 7 Home Premium (64 bit) Samsung laptop.The lap uses Realtek Audio Drivers. The audio (both laptop speakers and output in the earphone) works perfectly in Ubuntu, but the earphone does not work in Windows 7. The speakers work perfect in both the OS s. Before this, everything was normal in Windows7. I googled it quite a bit for the the last couple of days.
Some things I have found and tested are
When I shutdown the laptop and just remove the battery (to reset the power connection) and boot directly into Windows, everything works perfect. But when I boot into Ubuntu first and then to Windows no output in the earphone.
When I restart from Ubuntu or Windows and boot into Windows first, same problem persists.
I have also updated all the drivers (both Realtek and from Samsung). That does not solve either.
I have tried everything that I found ,but still have the problem.
Would be glad if any of you could help me out. Do ask me for more details if you require any.
Thanks and Regards Shree
PS.. I am pretty sure no volume mixers are muted, and speakers are the default playback devices and microphone is the default recording device. In fact I can record any time on Windows but it is just that I cannot hear audio playback in the earphone. And sorry for keeping it a bit long.
