I've just installed Debian Linux (Wheezy) and I hooked up my speakers and don't hear any audio from flash or sites that commonly stream sound. I know I would need 'alsa' so I manually installed 'alsa-base' but that did nothing. How can I properly troubleshoot my system and verify I have the correct packages for sound to properly render on my new Debian Linux machine?
I did verify my login user is a member of the 'audio' & 'cdrom' group.
users cdrom audio
