cs46xx on Voyetra turns off amp while CD plays
Last modified: 2014-03-16 22:15:52 EDT
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
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
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
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.
