| Subject: ALSA: hda - Sleep for 10ms after entering D3 on Conexant codecs |
| |
| From: Park Ju Hyung <qkrwngud825@gmail.com> |
| |
| commit f59cf9a0551dd954ad8b752461cf19d9789f4b1d upstream. |
| |
| 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. |
