1.- I did not have audio in my new Desktop, yesterday I followed the instructions here
and the host had audio.
2.- Today I was trying to enable the audio in my virtual machines I reinstalled VirtualBox Additions in the Win 7 and in the LXDE and did not work. Then for the LXDE guest I installed through Synaptic the following packages
Immediately after installation I enabled it through PCLOS Control Center - Hardware - Sound, and reboot, but the sound did not work.
3.- So I opened a youtube video in the host and guess, no audio! so I checked the Sound setting on PCC and it is like yesterday when it worked. The host Sound Configuration in PCC is this:
3.1 Driver Intel HDA driver (snd_hda_intel-ALSA)
the one automatically selected by the LXDE Installer.
3.2 Enable PulseAudio, marked
3.3 Enable 5.1 sound with Pulse Audio, marked
3.4 Enable user switching for audio applications, not marked
3.5 Use Glitch-Free mode, marked
In "Advanced", all values are the default ones.
4.- I have a Motherboard ASUS P8 Z77-VLX with audio Realtek ALC887
, 8 channel HD Audio Codec and an NVIDIA GEForce GTX570HD. My headset and mic are connected to the motherboard connectors. In PCC there are lots of sound drivers and I do not know which one should the the right one.
5.- I do not understand why the Host audio was working yesterday and not today, today I only changed the virtual machines, not the host.
Sorry for so many questions, but if I resolve this issue, I thing I will finally get my Desktop working fine.
