Hi. I have now successfully installed "devuan ascii _2.0.0_amd64 desktop-live.iso" on an iMac.
Everything works great, except the sound quality is so-so.
The sound worked before on the imac, so I think it is not a hardware problem.
It is a 64 bit system.
3.06 GHz Intel Core 2 Duo processor.
Model: A1225
24" - seems to be from 2007.
Question: What might I do to improve the scratchy sound? It is present with Youtube (through various browsers) and Xine, and VLC.
Thanks for ideas/guidance.

Obvious ones:

• Drivers
• Codecs. Have you vlc? Have you gstreamer? What Have you
• Try the same video/mp3 in another OS/tablet. Is the sound ok?
• show us the lspci o/p for youe card. Try 'lspci -v |grep - iC 10 Audio

Thanks for your help.

Yes, I have vlc, as stated, and tried Youtube. I could try gstreamer also. I tried the video elsewhere, and it is fine. I will try to run
['lspci -v |grep - iC 10 Audio] in command line. Is that typed right? Is the first [']needed, before lspci?

I can also look into the "oss sound driver"

Give me a day to work on it. I am in a different time zone, so it might be a while.

Thanks again.

Forget OSS. It was a good idea in the 90s, when you still had ISA sound cards until people decided it was a very bad idea an wrote alsa. Alsa was a bad idea until people wrote enough drivers, then it was awkward to configure but worked. Now people are writing pulse, which is a mystery for users, but makes things handier for programmers but is really just piggy bloatware. The thing to remember about pulse is that there's always a server running; so you can just type 'pkill pulse' into Alt_F2 or any terminal, which kills it. But it respawns, so it isn't gone but your config is updated.

Although the solution will not be the same; I have a thread with a similar issue, but with different hardware. But I went through things methodically, so you might want to look into some of the things I did to try to find a solution in that thread:

Hi all,
I ran ['lspci -v |grep - iC 10 Audio] in command line and it said "No such file or directory" I then tried it without the first apostrophe symbol, and it just gave me a ">" sign - not sure what that means.
Thanks.

My bad. The exact code without typos is That should provide the output of lspci with 10 lines of context on the Audio device, your soundcard

Archwiki suggests kernel fixup available for ALSA to get subwoofer and jack-detection working

Thanks.
lspci -v |grep - iC 10 Audio --just gave me a ">" sign - not sure what that means.

I will check out the wiki archlinux info and get back to you.

Probably you had a stray ' or " in there, as the > means it doesn't think the line is finished.
