[Impact]
Headset Mic plugged into Dell WD19TB dock stops working after suspend/resume.
[Fix]
According to alia-lib's document, to make PCM properly leave suspended state, we only use snd_pcm_resume() if hardware support PCM resume.
For hardware that doesn't support PCM resume, like snd-usb-audio on WD19TB dock, we should use snd_pcm_prepare(), snd_pcm_drop() or snd_pcm_drain() to make device leave suspended state. This patch defaults to use snd_pcm_drop() to achieve the goal.
[Test]
1. See if microphone on snd-usb-audio works in gnome-control-center/cheese.
2. Suspend/resume.
3. See if microphone still works in those apps.
I can the issue is fixed after each suspend/resume cycle.
[Regression Potential]
Low. This fix makes PCM suspend/resume more reliable. No functional change is intended. I also don't find any regression during some smoke test. |
