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.
