Re: mplayer won't play audio CD

[Wellington Terumi Uemura]

Yes, I use source from HDtracks, ProStudio Masters, 7studio, Bowers & 
Wilkins Society of Sound, Primephonic, DSD, along Hi-Res 24-bit/192kHz 
capable equipment.


I'm not a big fan of downloading mp3, I rather like to convert my own 
stuff to hear it in FLAC or AAC. Music in general this days are crap, 
the ones that play in the main media in special, not to say the quality, 
most of then are over saturated, over compressed (loudness war).


Checking some with Audacity you can see a red block from start to finish 
of the song.


Not big fan of vinyl and tube/valve amps. ;-)

I don't have space limitations around here, as long as it works. ;)
Maybe I should move to another Linux distribution specific for my needs.
http://www.ap-linux.com

I don't know if is because I'm aging and now I've other priorities, I 
don't fell like messing with Linux too much. Before I used to compile my 
kernel specific to my machine, with specific cflags and all.


Now I just want the damn thing to work ;)

Too bad I can't code, otherwise I would. Tried to learn a few years ago, 
all I see is "do this, do that, hello world" but I miss some kind of a 
logic behind it. Is just like OS's, if you get the logic behind it you 
can use any, it doesn't matter the brand.

Also perhaps verify in a mixer program (alsamixer, e.g.) that cdrom audio output

Maybe there's no audio cable between the cd drive and the sound card.

Help with what? export is only intended to make the variable empty
so that the message above does not appear after a su to root. It does
not turn a non-working audio into a working one.

Your original problem (no CD audio as a user) has been solved. No audio
as root is an interesting problem but hardly critical. I have no issue
with audio as a user or as root when playing a CD. Reviewing any tweaks
you have made to the system is advised.

Well I'm still reading that "pulseaudio in normal user mode will allow
only the active session as marked by ConsoleKit to access the audio
hardware." 

So it would seem that you'd have to run pulseaudio as a system-wide
instance for this to work (sound for your regular user and root through
pulseaudio, configured by each with pavucontrol).

 XDG_RUNTIME_DIR=/run/user/0 mplayer ... ?

nor

 export XDG_RUNTIME_DIR=""

The message (from pulseaudio, I think) is valid. su has been used to
gain root so $XDG_RUNTIME_DIR is inherited from the user's shell.
XDG_RUNTIME_DIR should be specific for each user, not shared.

 export XDG_RUNTIME_DIR=""

can be run before mplayer to not see it.

Yes, the error message remains also with sound files, so it actually does not

I don't know. Actually I'm using
MPlayer2 2.0-728-g2c378c7-4+b1 (C) 2000-2012 MPlayer Team
which is a real package.

But the thrust of my post was two-fold: (1) get configuration
files out of the way, and (2) get pulseaudio out of the way.
I'm assuming people can handle reading the man page to adjust
the command line arguments (eg my long options _require_ --ao
and --noconfig to parse correctly; the OP seems to get away
with one hyphen).

Were I using stretch mplayer, I would have posted yesterday,
but the thread seemed to have wandered up blind alleys (group
membership, device aliases, etc) without addressing the error
messages posted (missing sound device files, alsa/sdl errors).

Yes, I've used cdplay on occasions, and it's a lot quieter than
cdda because the disc so slowly comparatively, though I always
use eject rather than cdeject as the latter has given me problems.

Of course, with a laptop, you're at the mercy of the constructor
as to whether the analogue link exists.

Linux sound is complex enough that, once things work well enough,
I prefer not to disturb them, which is why I beg your forbearance.

Hi,

To be exacting, i only doubted the idea. It got disposed by the report
that a normal user (the desktop starting user ?) can have success.

The hardware is at least not yet proven to be faulty. I am not really
aware whether it was reported that one of the successful CD play attempts
was acoustically flawless. (E.g. by pure Grunge with all its fine nuances.)

Did you try as superuser ?

I have the gutt feeling that user "root" is slowly being moved into
the role of the man who once was indispensible but now is just an
old fart whom the young agile people don't trust to do anything useful.

Curt noticed this message in the original message:

So if the software means that the superuser is not welcome, then this
should be discussed with the software's Debian maintainer or its upstream
developers.

The other messages in the original post
  https://lists.debian.org/debian-user/2017/06/msg01215.html
look like software or system management problems, too.
(But hey, i am no expert with software that causes flamewars whenever
 its name gets mentioned.)

It has been deprecated by MMC-5, which is the first MMC version mentioning
Blu-ray drives. So one could assume that BD drives would not support the
PLAY AUDIO command. Nevertheless, my newest two BD drives announce its
availability by feature 103h. Only my good old LG GGW-H20 does not offer it.
I assume the ASUS and the Optiarc burner have an audio socket at their
backside. The last one i had with front earphone socket was a Lite-On CD
burner from 2003.

As someone whose use and knowledge of anything other than vlc is
minimal I did this on unstable and got

 Unknown option on command line: --noconfig=all
 Error parsing option on the command line: --noconfig=all
 
> Currently I don't have mplayer installed, only mplayer2.

How relevant is this statement to the issue?

  Package: mplayer2 (3:0.23.0-2) 
  transitional dummy package for mpv

  This is a transitional dummy package to get upgrading systems to
  install the mpv package. It can safely be removed once no other
  package depends on it.

Once Thomas Schmitt had disposed of the idea that mplayer requires a
cable between drive and sound card it comes down to software and not
hardware.

(I use cdplay from the cdtool package quite extensively, especially in
scripts. If the OP had been using cdtool, Curt's cable suggestion would
have very likely been correct as cdtool uses the analogue play method).

I installed mplayer on a machine (which has pulseaudio) yesterday. There
was no problem with playing an audio CD, but I did not go in for any
customisation, which is probably not the case with Rodolfo Medina.

should deal with that.

Without that parameter, I (mplayer2) get an extra line of output:

Actually, upon further reflection, the root error message from his
original post was:

 XDG_RUNTIME_DIR (/run/user/1000) is not owned by us (uid 0), but by
 uid 1000! (This could e g happen if you try to connect to a non-root
 PulseAudio as a root user, over the native protocol. Don't do that.) 

which might mean the incriminated environment variable is being inherited from 
his
user shell (if he used 'su' maybe).

So, in order obviate that, he should--well, you tell me.

First, it would seem sensible to clean up your first post by
revealing the output from, say,

# mplayer --noconfig=all --ao=alsa cdda://

Currently I don't have mplayer installed, only mplayer2.
I would point out that this command still reads input.conf
files so you might want to move them out of the way too.

Secondly, most of the error messages involved alsa rather
than the CD player. How does root get on with playing
sound files from other sources?

Thirdly, what's in /dev/snd?

There's no need to apologize. As for the root problem I don't believe it
is a problem in the sense you mean it (I think). pulseaudio is not
intended to be run as root (that's what I'm reading on the innertubes). As
usual my understanding of the whole kaboodle is quite fragile, however. Also
I believe pulseaudio is configured per-useredly.  IOW you'd have to
configure it for root in order for it to work (for root). Maybe.

Unless you're not using pulseaudio, in which case...

Now you see who's stupid.

The problem disappears running mplayer as:

Recently I noticed that mplayer, when playing audio CDs, is always complaining
this way:

 `Audio device got stuck!'

, and sound continuosly `jumps' so becoming unheardable, and I thought it was
the device's hardware fault.  But vlc plays well with no at all that problem.

I had settled the alias: `mplayer = mplayer -demuxer lavf'.  After removing it,
now mplayer works regularly over CDs (apart from the above problem) as a normal
user.  Instead, as root, the problem I started this thread with remains:
mplayer doesn't work...  Not so great a problem, after all.  But isn't it
strange that something user can do root can't...?

This doesn't help.  But, I repeat, mplayer now works and read audio CDs from
normal user.  Only, it continuosly `jumps' and gets stuck.  (I will open a new
thread about that.)

Not quite what you wanted but you can now play an audio CD.

We suppose the CD ROM shows activity (a blinking light) with
'mplayer cdda://' even though there is no sound output.

How do you go on with

  'mplayer -ao alsa cdda:// ?

This could also be a software issue but this time involving pulseaudio.

Yes, but that time mplayer won't play files either.  Now instead mplayer works
with mp3, audio files...  but fails only with audio CDs.  That time the problem
was solved installing alsaplayer-alsa and pulseaudio.  Now I already have those
packages in my system...

How about

  vlc cdda:// ?

`mplayer -cdrom-device /dev/sr0 cdda://1' gives the same error output as
`mplayer cdda://'.

I doubt that mplayer would use the PLAY AUDIO command to let the drive
send an analog signal to the sound card. I rather assume it uses READ CD
to get the 16 bit digital audio data and then processes them like other
input.
So no audio cable from drive to sound card would be needed.

So my desktop user got an extra permission to read and write, regardless

It is worth noting that local access to the /dev/sr* device does
not depend on being a member of the cdrom group, Using 'ls -l':

 brw-rw+ root cdrom 11, 0 June 30 11:15 /dev/sr0

The "+" is a result of 70-uaccess.rules in /lib/udev/rules.d. It
indicates an Access Control List (ACL).

The installer has always  put the first user into the cdrom group. It
is questionable whether this is necessary any more.

How about giving it the full path:

 mplayer -cdrom-device /dev/media/cdrom cdda://1
 mplayer -cdrom-device /dev/hdb cdda://1

or wherever the device exists on your machine.

Also perhaps verify in a mixer program (alsamixer, e.g.) that cdrom audio output
isn't muted.

Maybe there's no audio cable between the cd drive and the sound card. 

;-)
