+As always when it comes to diagnosing problems with !VirtualBox the appropriate VBox.log is useful to have. To gather more verbose information about the actual audio state, please do the following:
+
+'''Tip of the day''': Best is to copy & paste the following commands to avoid typing errors.
+
+ * Shut down all VM instances and !VirtualBox programs, including VBoxSVC.
+    1. On '''Windows''', run
+{{{
+setx VBOX_RELEASE_LOG "drv_host_audio.e.l.l2.l3.f+drv_audio.e.l.l2.l3.f+audio_mixer.e.l.l2.l3.f+dev_hda_codec.e.l.l2.l3.f+dev_hda.e.l.l2.l3.f+dev_ac97.e.l.l2.l3.f" /M
+}}} 
+       on an Administrator command prompt to set this on a system-wide level (required).[[br]][[br]]
+    2. On POSIX-enabled hosts like '''Linux, Unix or OS X (MacOS)''', open or run a terminal as '''root''' and run
+{{{
+export VBOX_RELEASE_LOG=drv_host_audio.e.l.l2.l3.f+drv_audio.e.l.l2.l3.f+audio_mixer.e.l.l2.l3.f+dev_hda_codec.e.l.l2.l3.f+dev_hda.e.l.l2.l3.f+dev_ac97.e.l.l2.l3.f
+}}}
+  
+  * Close the Administrator / root terminal
+  * Open a new terminal as '''regular user'''[[br]][[br]]
+     1. On '''Windows''', verify that the changes were applied correctly be running
+{{{
+echo %VBOX_RELEASE_LOG%
+}}}
+     2. On POSIX-enabled hosts like '''Linux, Unix or OS X (MacOS)''' verify that the changes were applied correctly be running
+{{{
+env | grep VBOX_RELEASE_LOG
+}}}
+  * Start the !VirtualBox Manager and start the VM you want to diagnose audio for.
+  * Perform and reproduce the audio operation.
+
+
+== Ok, all done! What now? ==
+
+Please collect the VBox.log from the host, pack it (ZIP, RAR) into an archive and submit that archive as part of a new or existing bug report at our [https://www.virtualbox.org/wiki/Bugtracker public bug tracker].
+
+'''Note:''' Without the log file we cannot diagnose your issue, so please make sure to always attach that. Thank you.
