This may seem random but I have not had sound for flash for 2 months and if you have not noticed it has taken over the net (sorry proprietary bastards). There are huge numbers that have various sound problems because of the ancient way in which they access sound in windows. I have recently solved my issue so I am shouting it from the rooftops in case it can help someone else.

Here is a link to a good complete troubleshooting page:

The site does not apply directly to 64bit versions and so here are some specifics fixes and one new for both 32 and 64 bit ie the registry key permissions which was in fact my 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.

1.Launch Registry Editor by typing regedit at Run command.
2. Navigate to the following registry key:

For XP and Vista 32Bit:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

3. 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”.

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.
