In Windows 7 using Firefox 13.0.1, the flash process spawns a unique volume mixer in the Windows 7 Volume Mixer panel every time the plugin restarts (ie, starting Firefox or when all flash containers are closed and a new one is opened). This unique volume mixer is set to 100% which means it blows out my speakers every time it loads. This is incredibly annoying and all the other programs in Windows 7 seem to be able to remember their volume settings except Flash. I would downgrade but because Flash is the most common malware vector I have to keep it up to date. Please fix.
Could you please open a new bug on this at bugbase.adobe.com? In addition, if you are intersted in trying a test build out that addresses other sound issues please see this post.
