Thanks for all the help ralph.ronnquist. My "solution" of just using Parole to play CDs is mostly okay for me. Maybe one day I'll bite the bullet and learn scripting.

Thanks ralph.ronnquist. That's an interesting link. I tried the same thing the guy in the link did, switching the engine from mpv to smplayer. I got a very similar error to his. I'm not versed at all in scrips or wrapper scrips. I'll have to research it when I find the time. One question though, how do I find out if mpv is a script already, as you state is a possibility?

Also, I pasted over your quote of José Jorge to my post in the SMPlayer forum. Hopefully they'll get this fixed.

I notice at the bottom of the log file it says "No such file or directory." Does that point to a missing intermediate directory?

As a test, I installed Parole Media Player, and it plays CDs just fine. Does this give a clue as to what is SMPlayer's problem? I'd just use Parole for everything (because I hate having two apps that do the same thing), but when playing videos it puts a thin green line down the side of videos, just like Totem and Mint's Xplayer used to do for me.

EDIT
I just did a web search for "debug argument to start mpv with" and didn't find anything.

While I'm not the OP, I avoid PulseAudio because I don't like the philosophy of its author; that has nothing to do with tinfoil hats.

Thanks MiyoLinux. I guess I can mark this now as "solved."

Yeah, that was it. I found it, that's why I deleted my post. I just now burned it to a DVD, so after I'm done with this post I'm going to reboot and see if it works.

@GNUser: Thanks for the additional info!

Thanks for you reply, golinux. A few things: one, out of curiosity I opened synaptic and redid my search of "iso," and refractasnapshot was in the list. Somehow I missed it yesterday. Next, I assume refractasnapshot doesn't have a gui, as it's not listed anywhere in the start menu?

When running it in the terminal, I get this message:

configfile is /etc/refractasnapshot.conf
uefi setting is yes

 Warning: grub-efi-amd64 is not installed.
 The snapshot will not be compatible with UEFI.
 To disable this warning, set make_efi=no in /etc/refractasnapshot.conf

My first question is how do I know whether I need to download grub-efi-amd64, or just disable the warning (as is said in the last line)? If I should install it, I'm concerned that it will mess up my system. Will it change the way my system boots?

EDIT:
Found out you can download the gui from sourceforge, which I did.

Thanks siva for sharing your experience with deleting avahi. I also got the same things as you and golinux.

If you go back, you'd see that I did say I'd research it when I have the time. You know, I have a full time job, and a wife and kid that takes quite a bit of my time. I don't live on the computer. I really don't know what I said to warrant such passive aggression. And who was whining? That crack was unwarranted.

I agree with spartrekus that pulseaudio is crap. I avoid anything made by its author.

When I first tried Devuan, I had no idea which installation option I should use. So it was confusing for me. And the one I did download didn't work. Maybe I downloaded the wrong one? Thankfully the Miyo installation file worked. I can appreciate where esr is coming from on this issue, and most of the other things he has said. If he can start his own derivative of Devuan, I'd help any way I could (which would probably be limited to be a beta tester).

He has tried a Devuan install:
