Lastly, I have verified that my sound works outside of virtual box. What does it mean when I get the Unknown hardware: 'Dummy' info? No audio device? Is there anyting jumping out from what I have above? Even a nudge in a general direction would be great. I know so very little about audio and ALSA. At least not to me, since I don't have nf However, this doesn't seem applicable to Android. Several webpages have content similar to this one saying to modify /etc/modprobe.d/nf and add options snd-hda-intel model=CORRECT_MODEL and this appears to help a lot of Linux users.

Since Android is basically Linux, I thought I would be able to translate a Linux solution. While this looks a little more promising, I still have no audio. With the ALSA driver and Intel HD Audio controller I get the following from alsa_ctl init Unknown hardware: 'HDA-Intel' 'SigmaTel ID 7680'. This looked very wrong to me so switched to the Intel HD Audio as the other question did. Hardware is initialized using a guess method With the ALSA driver and SoundBlaster controller I get the following from alsa_ctl init Unknown hardware: 'Dummy' 'Dummy Mixer' This question got me to look at some of the ALSA commands to see what I could find, but I'm not getting anywhere with it. The Android-x86 VirtualBox tutorial and other online resources directed me to use the ALSA driver with SoundBlaster 16, but this has not worked. I have worked through some of the troubles I have come across (by not having an ISO for my device), but I haven't been able to get the sound working. This particular ISO is not for the laptop, but of all available ISOs it works the best. I've setup an Android-x86 image (4.0-RC1-eeepc) in VirtualBox on a Dell Latitude D820.
