Title: HDMI audio is severely distorted. Status in alsa-driver package in Ubuntu: Confirmed Bug description: I have recently installed Ubuntu onto a newly built computer with an ASRock H87 Performance Motherboard. I am using a TV monitor for a screen, connected with HDMI. The visuals work fine but the audio is severely distorted and echoes. When testing the sound in the hardware settings, it sounds like "FRONTFRONTFRONTFRONT" with static or overdrive getting more and more prominent as the sound goes on. I have changed the Alsamixer levels but found no change. The built-in sound card also shows up when i look for it as per the Sound Troubleshooting page.
