CMUS library view and MOCP volume control questions

Ghost-Order · 02-18-2020, 09:16 PM

For Cmus, is there a way to display the music in the first view according to the album name and not the artist? At first I liked very much this music player but when I wanted to listen an OST album that contains music from different artists I have to create a playlist to group all the music from an album. A solution was playing music from the browser view (5) but the problem is when a track finish it starts playing music randomly from the sorted view (2).

So because of this I search for other terminal like music player and I found Mocp, and at first it seems to do the job but then I realize the volume control was global. Is there a way to control the volume in a way that only affects the music player?

Both players are of the sort that requires you to read some documentation.
I don't use cmus, but for MOC I can say: "softvolume" exists. I don't remember if it's necessary to edit the config or accessible from the UI.
You can also tell it which sound architecture to use.

Yeah, I read both manuals but I couldn't find anything regarding these subjects. I think 'softvolume' and 'sound architecture' are the keywords here, thank you I will search more about that.

Ok I found that the issue here is the sound driver, I was using mocp with the default configuration and for my purpose being enabling a 'local' volume control instead of the 'global' aka 'master' one that comes with the program by default I needed to enable the Jack Server, because that would make the driver run as a service (sorry if this sounds awfully redundant but I was a Windows 10 user and all this things are new to me) and that way it becomes a kind of separate entity from the music player, please correct me if I'm wrong or misunderstanding how this works.

So when I enabled the jackserver and then started mocp, it indeed started but before that it showed me a message saying that I needed add this line in /etc/security/limits.conf

Code:

@audio           -       rtprio          99

After doing that I start again mocp and it again started but before it showed a message saying that although my system had an audio group I myself was not member of it so I did:

Code:

sudo usermod -a -G audio "my user name"

as the message said, then I restarted the pc.

Now finally the master volume changed to 'soft-mixer' and now the volume control does not affect my system globally. However, again, before mocp starts the terminal displays a message with the following:

Code:

could not open driver .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory

JACK compiled with System V SHM support.
cannot lock down memory for jackd (Cannot allocate memory)

ALSA: use 2 periods for playback
JACK: unable to mlock() port buffers: Cannot allocate memory
JACK: unable to mlock() port buffers: Cannot allocate memory
JACK server started

Now I have two issues that maybe are related to that message.
1- From time to time (in a 30-45 secs interval approximately) the audio quality drops for about 1 or 2 secs
2- I can't play tracks from playlists, I hit enter again and again and nothing happens.

Anyone can give me a hand on this subject?

Sorry but you are vastly overthinking this.
There was no need at all to make such deep changes to your system.
I am currently not using MOC, but I reinstalled it and must say I was wrong: Softvolume does not do what I thought.
Question: what sound architecture were you originally using (before you messed your system up)?
I guess pulseaudio.
There are two approaches to use MOC with pulseaudio:
- through OSS - but I don't know how that works

- install 'apulse' and use it to start moc: 'apulse mocp'
