To my knowledge this is indeed an ALSA issue: after resume the PCM
device is not properly restarted by the kernel drivers. PA doesn't
notice that, ALSA never asks for new audio data, all current and new
audio streams appear stuck.
In theory ALSA defines a proper state machine for dealing with system
suspends. The issue is just that it doesn't work on some drivers on
Please report this issue to ALSA upstream if it persists with the
newest ALSA driver.
