What is the output when you add -v to the aplay command line?
If you still have the old Centos, is there any difference between
the working and broken -v outputs?
I got back to the old system and compared the -v output from Centos-6
with the one from Centos-8. A diff shows only the "boundary:" values
differ:
26c26
< boundary : 6755399441055744000
---
> boundary : 1572864000
49c49
< boundary : 9007199254740992000
---
> boundary : 2097152000
with the larger values being from Centos-8.
I attach the output from centos-8.
Hope that helps, AG
