In the cs46xx driver, it turns off power to the amp even though a CD is playing. This causes the CD audio to drop out after a few seconds. Ideally, you should be able to have it somehow just leave the amp on, either by default, or with a module parameter. (or make the power-saving turning off of the amp a module parameter.)
Ok I think the right answer is to turn the amp on whenever the CD input is selected. I will investigate if this is doable.
Still failing in RC2.
I have a possible fix in my build tree. This will go to Bill once I've tested stuff
There is a test patch for the power on/off issue in 2.2.18pre2 - its not perfect it checks MUTE when it needs to check MUTE | vol ==0 for off. That is next on the list to try Alan
Bill implemented the volume 0 or muted solution and it seems to work sanely
This looks like an accidentally not closed bug report, closing now.
