Similar behavior was experienced with applications like Jabber and Skype4Business (this is using the Alsa driver with Intel HDA virtual audio controller). One interesting note: when using YouTube in the Windows 10 guest, I'd get utterly horrible audio (resonance/echo, clipping, popping, stuttering) for the first 10 seconds of audio playback, and then it gets better after that (some minor popping, but at least usable). I never had this issue with Win7 圆4, but can't speak for pre/post Win10 anniversary update. I just tested 5.1.28 and 5.1.30 on Ubuntu 16.04 LTS 圆4 (host) using a current Win10 圆4 guest: issue persists. HOST: Linux 4.10.4-1-MANJARO #1 SMP PREEMPT x86_64 GNU/LinuxĪLSA: Advanced Linux Sound Architecture Driver Version k4.10.4-1-MANJARO. Install the ac97 driver as specified in the stack overflow link.

Windows will show as audio device missing which is expected.

Change the 'Audio Controller' to 'ICH AC97'.

(Pulse Audio also works but it still had stutters)

Change the 'Host Audio Driver' to 'ALSA Audio Driver'.

Open the Settings navigate to Audio section I am finally able to get the audio working by doing the following, Looks like the problem resides in the HD Audio Driver. Host: Windows 7, Virtual box 5.1.20, Guest: Windows 10 Pro This 'temp' (which might be long term -) ) solution works! Thanks a lot billikumar

The solution proposed by billikumar has also worked for me. I'm not sure if I did something wrong but I followed instructions carefully and didn't notice any blatant errors. I'm attaching my Logfile, however, like Olem mentioned above: I followed all the instructions for Audio Debug but the 'Audio: Verbose logging enabled' does not appear in my Vbox.log file either. Eventually video will lag behind the audio by 2-5 seconds. Videos (YouTube, Netflix, etc) start out acceptable for the first 30-60 seconds or so and then the audio/video falls out of sync. Also, I'm not sure if others have mentioned, audio and video sync is lost very badly.

When more than one audio source opens up (such as streaming audio from a player and then audio starts on a web browser) the audio starts crackling worse - sometimes it gets so bad that the streams become unrecognizable and you can't actually tell what is being played. I notice crackling of audio when just playing audio streams. Changed every setting remotely related to hardware usage and/or virtualization, changed guest audio drivers, changed host audio/video drivers and settings throughout the OS, even did a clean install of a Windows 10 guest and the same issues occurred. I've tried every combination of troubleshooting in the book to resolve the issue. Seemingly all started after the Anniversary Update - like most others have mentioned. I've been dealing with the same issue with a Windows 10 host and Windows 10 Guest for quite some time now. Finally signed up for an account to add my two cents in as well.
