I think you are misunderstanding what was happening.

If the card is set at 48000 with the new drivers, RD cannot "see" the card at 
all. It is reported as not being installed by RD Admin.


If rdalsaconfig is set to 44.1 and RD is restarted, the card is seen as 
installed by RD, but on playback the audio becomes noisy and corrupted.


If you go into rdalsaconfig, change the sample rate to 48000 and restart the 
daemons, the audio card is no longer reported as installed.


The card and the machine worked properly under 48000 when the appliance was 
initially installed. Something that gets updated during the OS update process 
is changed and causes this issue with my machine.


It is simply going to receive GPI closures and play back station ID's, so I am 
not really wanting to do much with this unit other than take the path of least 
resistance to get it to function. If it were one of our playout machines, that 
would be a different story.

It's not that it is happy...Alsa defaults to 48kHz in RHEL/CentOS. What
this does is change the default rate. If you look in the RD logs you
will or should see the error where this happens. You also need to make
sure RD is set at 44100kHz also in the Admim settings.


Could you try this before going further:

### put in  /root/.asoundrc

pcm.!default {
type rate
slave {
pcm "plughw:0,0"
rate 44100
}
}
