In the alsa-info.txt, I found some unusual info, I have no idea why those commands failed, I never met this situation before. Why alsa commands can't work on this machine?

From what I can tell from the journalctl printout this appears immediately after either bluetoothd or pulsaudio crashes. This is happening multiple time each day for each user. It doesn't happen to all users, but the reports seem to be getting more frequent by the day. From what I have noticed there recently was an update for pulseaudio and its bluetooth integration.
