i dont know what you are talking about. the volume knob i am talking about is a physical controll wheel on the toshiba portege R500-12P Model PPR50E-06W09QGR notebook or netbook.

in the meanwhile since my report i tested MANY more linux distros. ubuntu up to 16, mint, arch, debian 8 . If the distro came up to life on it, ALWAYS the Audio remains silence. BUT...it was seen that the internal microphone works, since graphical mixer show inbound VU levels on the internal mic. however still any distro fails on the sound output. neither through speaker nor headphones.

today im running debian 8. behaves just the same as ubuntu.

UPDATE:

Problem solved.

i tested several big distros the last days and weeks on that toshiba r500 12p notebook / netbook without any luck or sound. so today i decided to temporarily reinstall windows 7 to try out sound there and see if i can unlock or unmute the sound. even with the original sound drivers for win7 the sound remained SILENT, just as within linux. so i did another google search for that problem, but excluded linux and there i found some threads on several forums that had just the same problem. on one thread i found the following link to some toshiba tool for windows, that is supposed to "unmute" or "disable mute" on the soundcard.

Sound Utility to Turn Mute Off |http://support.toshiba.com/support/viewContentDetail?contentId=1671893&pf=true

i dont know what exactly this tool does and where, but it worked!! installed, runned, rebootet and there where sound again under windows. next i installed debian 8 again and STILL SOUND at last.

so it seems the problem is relative common with lots of toshiba notebooks.

however...what is strange, i have been unable to unlock/unmute any soundcard from linux using pamixer or pavucontrol . all devices and channels where unmuted and maxed volume. so to me it sems there must be another "mute" switch somewhere else, where the linux tools dont reach for.
