Hello,
I am trying to open a handle to dmix device and it fails with (Device or resource busy) error. On further debugging I found that it fails because it cannot open the slave HW device. This is the first instance of dmix but the slave open fails because it is already busy. I am trying to understand what kind of race condition could cause this situation but I cannot think of any.
Any thoughts how I could proceed? Maybe retry open is a good solution?
Any advice would be much appreciated.
Thanks
