Title: [MS-7968, Realtek ALC1150, Black SPDIF Out, Rear] Underruns, dropouts or crackling sound. Test tones work but sound immediatly returns to poor quality after completion. Status in alsa-driver package in Ubuntu: Confirmed Bug description: Using digital audio output on Intel driver. Sound from games is barely decipherable over the distortion/crackle. Playing test tones (left/right test and on bug report) work fine but the noise returns when the clips are completed. Tried tsched=0, hda fix 1 and hda fix 2. no luck yet When first added tsched command, it blurs the screen and no audio devices are available. remove, restart, re-add and screen and audio back but problem still present (maybe just spelt wrong first time?). Help appreciated.
