Error when using SSH in an attempt to change audio settings via terminal?

Help and Support Apple TV

First, Thanks to @sam_nazarko and the dev. team for all their hard work. I have been using Crystalbuntu & Kodi on my ATV Gen 1 for about a year and a half with very few issues and have been wanting to update to Kodi 15.2 with all the improvements. After about a dozen unsuccessful attempts, finally got it done using a 16Gb SanDisk Cruzer USB, Mac mini to create key, and the latest disk image dated 1/31/2016 for HDD. Everything seems to be working well; add ons installed, configured for HDMI out to TV (resolution at 720p as no CrystalHD card installed and Samsung TV is only 720P). I only use the ATV for streaming, and all the video seems to be working well. My only issue now is that I have NO sound…neither thru HDMI or optical digital passthrough. Audio output IS set for HDMI output, and Passthrough for digital. Searched the Forum for possible solutions and found 1 with a SSH command[quote=“michelb, post:2, topic:10287”]
amixer set Master 100% unmute > /dev/null 2>&1
[/quote]. When I tried to ssh into OSMC, I got the below alert.

Can’t seem to get around this. Anyone have any thoughts or ideas, your input would be greatly appreciated. I have “cut the cable” and really miss not having a working ATV. Thanks all.

If you would either have read the message or have goggled the error message you would already be up and running.

Everytime you reinstall OSMC a new SSH key is generated. As your ssh client stores the combination of IP Address/SSH Key it is complaining.

“Offending RSA key in /Users/owner/.ssh/known_hosts:2”
So edit that file on your PC and delete the complete line number 2 and you are done.

I’ve SSH’d to my box and nothing seems to happen for me. This is what I see in my terminal when I type it in.

osmc@osmc:~$ amixer set Master 100% unmute > /dev/null 2>&1
osmc@osmc:~$ amixer set Master 100% unmute > /dev/null 2>&1
