Sound volume resets at reboot since upgrade from Tiger to Snow Leopard

I'm seeing the same issue having upgraded from Leopard. Did you resolve the problem?

Ah, I see. The permissions are wrong. Deletion force new files to be create with the correct owner.

Thanks for the tip.

I'm having the same problem as the user above, but there is no Audio folder in my Library > Preferences folder. Any ideas for what I can do?
Thanks in advance!

renitasharma:

I had the same problem last night. Finally got it fixed though...

I was looking in the wrong library. Those plists are not present if you go through username>library>preferences...

Make sure you're looking in *Macintosh HD*>Library>Preferences>Audio.

There you'll find your audio plists. Delete them (Or temporarily move them elsewhere for peace of mind), reset your volume to where you want it, and reboot your machine.

Also, if you hold shift when clicking the volume, you can recalibrate your alert sounds level in the same way. At last, now my mac chimes at a civil level when I switch it on!

This doesn't work for me, but what it does do is play the alert volume feedback "pop" when that option is deselected in the Audio system preference & not play it when the option is selected. Thank you for that, even if it wasn't what was intended. Since I sometimes work with Macs connected to high power sound systems, it is good to know about -- you can't imagine how loud the "pop" can be until you hear it through a 20,000 watt concert PA! 🙂

Blootop: thank you so much! That was exactly my problem 🙂

Same problem with Snow Leopard, sound volume resets from mute to on when computer starts. I have followed previous posts and deleted the two files in HD library prefs audio, reset the sound prefs to mute but when I reboot the start sound is always reset to on. I have also done a PRAM reset and ran disk utility, repair disk permissions. Nothing has worked to date, annoying sound at startup is always back on at new startup. Any other suggestions?

This Snow Leopard sound issue sure gets around. Mine stared some time after the initial SL install. I have since done a compete erase and reinstall with no charges to my sound issue which is;

I can set my system volume level to about 10% but when I restart or startup the iMac the volume level defaults to the 50% setting. I have tried all the suggestions within this post with no fix. Applecare has no idea.

Anything new come on this subject since Oct.?

I finally fixed mine.

I had to delete the Audio folder referenced above in the preferences folder. I then went into Time Capsule and restored the folder from a few months back.

What was weird was that before when I deleted those Audio files, they didn't recreate when I restarted.

So, deleting the Audio folder and then restoring from TC worked for me.

explorz you are a GENIUS. I tried everything to fix the sound problem. I must have spent 2 days trying everything. Your method worked. Who would have thought of doing that. First time I had to use time machine back up and it payed off thanks now I can sleep tonight.
