Solve : Installed new GPU, now sound is broken.?

1.	Solve : Installed new GPU, now sound is broken.?
Answer» I put in a new ATI Radeon 4550 card today, everything works fine except my sound stopped working. In the sound options it says its working but it isnt. Someone on a different BOARD told me MAYBE to try setting my sound card as primary/default audio device. How would i go about doing this? Or is there another solution? thanksAny errors in Device Manager?none that i can see. under Sound, Video, Game CONTROLLERS it says High definition Audio DeviceTry to reinstall sound driver.ive tried everything. reinstalling different drivers and such. In sound options is says everythings working fine but still no sound. Is it possible my speakers/computer wont work with HDMI sound device?under the Playback tab in Sound options it used to say Realtek Audio something before i installed this new card. Now it says DIGITAL Output Device (HDMI) and it ways its "working"well CHANGE it back to your realtek one and all will be better. Just make sure you change it in both tabs
