[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 intended. I also don't find any regression during some smoke test.
