Just wanted to post to add to add a few more fixes for those who have experienced this frustrating problem.
Check if the file msacm32.drv is present in your Windows system32 folder. If not, copy it from another PC (that has the same version of Windows) and place the file in the system32 folder. This applies to Vista and 7 64Bit but in the SysWOW64 directory which is the folder for the 32 bit programs running on the 32bit virtual machine.
A very common sound problem is an incorrect or missing registry key for msacm32.drv discussed in the preceding.
For XP and Vista 32Bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
For XP and Vista and 7 64bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32
4. On the right pane, and check for existence of “wavemapper” registry subkey, the mail culprit
causing Flash no sound. If not found, create a new String
value named “wavemapper”, and give the entry value “msacm32.drv”.
If wavemapper entry is already existed, ensure that its value data is “msacm32.drv”.
5. In addition the permissions/security on these keys can prevent your browser flash plugin from
accessing them and preventing sound. Also if you receive errors editing or the key is blank you
need to check the permissions by right clicking on the key and choosing permissions. Choose
Advanced and make sure that the Administrators, System, Users Groups have "Full Control" under
permissions if not select them and click Edit and tick “Full Control" under the "Allow" column.
