Post Lost sound. May be related to VBox
I lost sound in my Mepis/Roadblock install a while back. I didn't notice exactly when I lost it, but I think it was about the time I was trying to get my sound working in Virtualbox. Which, my sound does work in virtualbox but not in my host Mepis system. Any ideas?

I have onboard sound, and I find that I can't have sound in Mepis and in my VBox XP at the same time. If I make use of sound in one, sound in the other does not work until I close XP. You may have the same problem - I've not found a way round it yet.

I also have an on-board sound chipset (and a pretty cr*ppy one at that). However, I don't have any problem sharing sound between the host and guest in VirtualBox. For example, You Tube clips play in both (but not at the same time of course), although the sound is a bit choppy in the guest.

You may have to play around with your VirtualBox Audio settings. I use these:

Enable Audio: On
Host Audio Driver: ALSA Audio Driver
Audio Controller: Intel HD Audio

If you are still unable to get audio in your host, then try disabling the audio completely in the guest. You might have to set the Host Audio Driver to "Null" to prevent the guest from grabbing the sound card.

OK, here is the current status. Rebooting does not change anything. I still have no sound in Mepis.


I tried to set the audio settings as indicated above. But that did not change anything. I even tried the 'null' setting. No go.

However, I thought I should mention that I used the OSS audio driver, along with the ICHAC97 controller to gain sound in the guest initially. And returning to that setting, I still have sound in the guest (WinXP) but not in host Mepis. I still think that Vbox has taken ownership of the sound card, but I can't seem to return it to Mepis. Although I supposed it could be unrelated as well. I have opened the audio 'Mixer' and nothing appears to be muted. I've mad that mistake before.

I am currently using Virtual Box to run a XP guest so I can run Quickbooks on my work computer.

As one relatively new to VirtualBox, a couple of comments:

- Install Guest Additions in the guest OS - It took me awhile to understand that it had to be installed in the XP guest and not from the Mepis host :bagoverhead:

- In the pop-up menu ( bottom middle ) while in the guest OS,
.......... Machine > Settings > Audio - Enable audio

My audio hardware
Code:
me@box:~$ inxi -A
Audio:     Card Intel 82801I (ICH9 Family) HD Audio Controller driver HDA Intel
           Sound: Advanced Linux Sound Architecture Version 1.0.23


Good luck :crossfingers:

In that case, I don't think VirtualBox is causing the loss of sound because none of the processes associated with VB can survive a reboot. I suspect you may have altered some of your MEPIS audio settings while setting up sound in the guest. Did you try running alsaconf (as root) in a terminal? Are your volume sliders turned up in Kmix? http://www.mepis.org/docs/en/index.php?title=Alsaconf

Hmm, I ran alsaconf and got a message that no PnP cards were found. I then tried 'alsactl store' but that didn't seem to do anything. So it does seem to be unrelated to Vbox but something else that got lost.
