ALSA: hda - Sleep for 10ms after entering D3 on Conexant codecs
On rare occasions, we are still noticing that the internal speaker spitting out spurious noises even after adding the problematic codec to the list. Adding a 10ms artificial delay before rebooting fixes the issue entirely. Patch for Realtek codecs also adds the same amount of delay after entering D3.
