My laptop goes to sleep automatically after about an hour idle.
Recently, when I wake it up, there are no audio output devices, neither
the internal speakers nor the headphone jack produce any audio, although
my computer still appears as if it's playing audio (e.g. youtube videos
will play, the sound test files act as if they are playing back).
Logging out fixes this issue, the speakers resume working on the login
screen. I don't consider this a reasonable fix, however, as it can
disrupt my work, requiring me to close and reopen all my software.
