Hi,

According to this groovypost tutorial, that was apparently last edited in 2021, it is possible to use task scheduler in windows 10 as alarm clock to wake up the computer and play music. As I’ve also written in the comments there a few weeks ago:

"For me the computer does 'wake up' and the task starts, but the screen doesn't turn on until you press a button and you don't hear the audio play until you log-in (with hp zbook G3, latest W10 and driver updates, and also same behavior with 3 other computers, so this seems standard behavior). When I just lock it, the music does start, when it wakes up from sleep without a password, I still need to press a button before I hear the music. It seems that there are some hidden assumptions on settings or hardware that I have not yet managed to find or that windows has prevented this from working with a recent update. Does this still work for any of you?"

Unfortunately, the post seems to be not very active, and no one has responded. As I’ve read here on the forum, (unattened) wakeup apparently has hidden settings, such as “System unattended sleep timeout”. Are there any more settings like this that could make the audio play over the speakers after an ‘unattended wakeup’ from (logged in but password locked) sleep with task scheduler?

PS Here is a thread that describes what I think is the same issue, but I can’t deduce a solution from the answers: Nikita Bespameat on Microsoft Community

PPS Version Windows 10 20H2 19042.1348
PPPS. Its not entirely clear to me how the audio works. In device manager under "Sound, video and game controllers it says Conexant ISST audio, driver provider Conexant, driver version 9.0.232.70. The speakers used under audio input and output say speakers (Conexant ISST audio), driver provider Microsoft, driver version 10.0.19041.1. (I cannot find much documentation on how this conexant audio device works. Does anyone have some pointers to documentation?)
