Failed to issue reset (I2C)

[mehrdadfeller]

Once in a while after a reboot, the audio stops working (even though the driver is loaded and detected by aplay -l). In dmesg log I get Failed to issue reset which means the driver failed to send reset command to the audio chip. Unbinding and rebinding the driver will make the audio work again. I believe there should be a few retries in the driver code below in case I2C bus is still not initialized during the boot or not yet stable after power up...

This happens once in a while after a reboot and the audio works otherwise. For more context, you can checkout this related issue and comments here:
