I am running Debian 8 on my desktop, Xfce - If that matters?My issue;New Logitech wireless keyboard, I hit the Mute button,the sound goes off, Almost automatically hit it again but the music doesn't come back on.Almost like I hit the key to hard and it killed the sound for good Lol.I have rebooted. Still no good.I plugged old keyboard in and tried muting un-muting.Have tried root & user accounts. No sound.Have tried another set of head phones.Have tried different media players and files.Have looked at my devices to make sure it still exists in lspci.It does.The mute/un-mute graphic works/changes and I can raise and lower thevolume bar graphically also.Have tried the alsamixer from terminal, sound devices listed butno good either.Any ideas or help would be lovely, I'm looking at a reinstall otherwise right ?Cheers
