Sometimes this achieve also better results since the dedicated processor can handle this computation really faster (since it's dedicated to that purpose) and achieve even more powerful features (never heard of pixel shaders in video games? they are used to improve the video rendered scene, and all that instructions are handled by the dedicated GPU)

Disabling harware acceleration means that CPU cycles will be used to process the audio output, but anyway the CPU load for audio output is not so heavy ;)

Maybe your audio card is good enought and the problem lays in bad coded drivers... if newer driver exists for your card then update them (note that not always updating the drivers means to improve the performance of the device, especially with multi devices drivers)

I understand. Thank you so much.
