Description Bill Nottingham 2000-08-16 23:09:09 UTC
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.


Comment 2 Dan Taylor 2000-08-21 21:40:04 UTC
Still failing in RC2.

Comment 3 Alan Cox 2000-08-22 17:06:18 UTC
I have a possible fix in my build tree. This will go to Bill once I've tested
stuff 


Comment 4 Alan Cox 2000-09-03 11:51:49 UTC
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


Comment 6 Michael K. Johnson 2001-12-06 17:29:21 UTC
This looks like an accidentally not closed bug report, closing now.
