Thank you Raymond for looking into this. Another thing that may be helpful: I removed a working vdi with Ubuntu guest o/s (version 15.XXX) running on the same host (current OS X).
In that guest, which also ran in VirtualBox, I had no problems with sound at all & I had installed a few other softwares (Audacity, some python tools,etc.). In the new guest, the only non-standard software is Ardour4 and there is no difference between the sound ability now and prior to installing that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605797 Title: [ICH - Intel 82801AA-ICH, playback] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1605797/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
