Substitute Audio driver for the Realtek driver

I'm not a big fan of the Realtek Audio Manager and drivers. I had problems with a desktop computer that used Realtek drivers. And I seem to be having the same problem on my Acer Aspie 150. Sometimes the audio stutters. At one point, I got a blue screen of death!!! I've read posts about others having issues with the stuttering and I can manage that. But for what I need the Aspie for (an amateur radio application), the Realtek system causes me grief. So, does anyone know of an alternative universal audio driver for the Acer Aspire One AOA-150 that would work and is not from Realtek????

For what it is worth, I want to use the Aspire One to decode analog and digital slow scan tv that is broadcasted over amateur radio frequencies, including myself.

Thanks.
