Title-Audio problem due to Windows 8.1 update message

I have HP Envy Sleekbook 4 which has Windows 8 installed in it by default. Few days back, when Microsoft released it's new version Windows 8.1, my laptop start showing message to update the current version of Windows 8 to 8.1. I ignored it everytime but now it is generating problems in the audio of my Laptop. One of the beats audio speaker has stopped working. I have to reinstall the audio drivers, everytime I login, to make them work properly. Please help.
