T60- SoundMAX HD audio issue

[kiranvanumati]

Hi,

I have T60 2007-C4U.
I used to get audio earlier but sometimes I see the default device as "Bluetooth Audio" and I don't see SoundMAX HD audio as my default device or in avaliable devices. And I cannot hear audio.
If I restart it sometimes I see SoundMAX HD audio as my default device and sometimes don't.
Can anyone help me?
