Hello community,
Host Windows 7 64 Bit
I recognized massive issues with audio active.
Setting Windows direct sound and ICH AC97 or Intel HD Audio. Leads into massive hang of the guest system. The are messages like "CPU 1 stuck vor 27 seconds ..."
In the VBox.log there are messages spammed "last heartbeat 10 seconds ago ...".
1st try: Install was Xubuntu 18.04 which got stuck after GUI login screen. Not able to load GUI in 30 mins.
2nd try: Installed Arch Linux with XFCE4, work until I tried to playback any sound, at the point I try to playback sound system hang.
3rd try, with Arch client running without GUI only command line: aplay Sample.mp3 system hangs.
I was able to break the playback with CTRL+C and shutdown the machine by shutown -h 0 (this action took two hours). Without sound playback the system goes down in a few seconds.
Even a host reset (CTRL+R) will not resolve the "CPU stuck for x seconds" messages.
As soon as Audio goes to Dev0 or sound is deactivated in the VM configuration there are no problems, aplay Sample.mp3 runs but no sound as it goes to dev0.
I installed the most recent audio driver for my DELL Latitude notebook.
I took a look inside Linux the audio driver configuration seems to be fine.
I configured linux audio to only use stereo playback.
ls /dev/snd
by-path hwC0D0 pcmC0D0p pcmC0D1p seq
controlC0 pcmC0D0c pcmC0D1c pcmC0D2c timer
lsmod |grep snd
snd_hda_codec_idt 65536 1

snd_hda_core 98304 4 snd_hda_codec_generic,snd_hda_intel,snd_hda_codec,snd_hda_codec_idt
snd_hwdep 16384 1 snd_hda_codec
snd_pcm 135168 3 snd_hda_intel,snd_hda_codec,snd_hda_core
snd_timer 40960 1 snd_pcm

soundcore 16384 1 snd
I have no idea what to do to get audio playback for the guest system.
*from hardening log I had to delete the 75% of the tail, because it exceeded the upload limit.
Thanks for suggestions and tips.
Best regards

Re: VBox 5.1x and 5.2x freeze/hang on any sound playback
I am running Linux Mint 19 and the sound is on, off, part on-off, etc.
This has been going on ever since 5.1. Each update, I think it will be fixed..... but it isn't.
1. I switch the Audio from PulseAudio ICH AC97 to PulseAudio Intel HD Audio and boot.
2. If the sound doesn't work, I kill the VM and
3. I switch the Audio back from PulseAudio Intel HD Audio to PulseAudio ICH AC97 and boot.
4. if the sound doesn't work, I kill the VM and
5. go back to step one.
6. if the sound works I keep the system up an running
BUT after shutting down I have to repeat the above steps.
There appears to be no rhyme or reason to why it works when it works.

Hello,
thank you for the suggestion
for me it doesn't work this way, every time I switch to ICH AC97 the hang/freeze symptoms appear at console login, audio playback not started at this time.
If I started Intel HD again system will boot fine but as soon as playback is tried - hang/freeze
Thanks for further tips and suggestions.
Best regards
