Hi,

I am unable to play music file using mpg123. I have installed it using source code. I am getting below error.

[root@localhost Music]# mpg123 Behene_de.mp3
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layers 1, 2 and 3
version 1.25.6; written and copyright by Michael Hipp and others

[src/libout123/modules/oss.c:174] error: Can't open default sound device!
[src/libout123/libout123.c:451] error: Found no driver out of [oss] working with device <default>.
main: [src/mpg123.c:308] error: out123 error 3: failure loading driver module


Please help..

are you using OSS as your sound architecture?
or are you using ALSA? can you tell mpg123 to use alsa?

Why did you install using source code and which guide did you use to do so? Which distribution are you using?
The error you see suggests that you have mpg123 set up to use the OSS sound device which, to me, seems odd.

I am new with linux and using centOS 7 .

@ondoho I don't know how to do it,

@123 I found an youtube video to install mpg123 player in linux using source code . So first I downloaded tar.bz2 file and then , ran compiler to compile it. After that "make" "make install". I hope this information is helpful .

Nearly every distro has a ready compiled version of mpg123 in its repositories.
So unless you intend altering the source code, you might as well just install it.

No, It was not in CentOS7 and when I type command # yum install mpg123, it showed nothing...

Red Hat has always been very cautious about including anything in their distros which might subject them to litigation. As a result, many multimedia applications which require restricted codecs are not included. In an abundance of caution, until recently RH would not include the mp3 decoder codec. However, there is an unofficial repository called EPEL you can add which will give you access to many packages which RH won't include in their official distro for legal reasons. Here's an article explaining how to add EPEL:

Once EPEL is added you should have a functioning mpg123 package available.

Here's the genuine answer from a fellow CentOS user!

CentOS is just a free Red Hat, but without software that's patented in the USA: if they gave you that, Red Hat would be sued. Also, Red Hat is small, as it only includes things which a large company might want and which Red Hat is prepared to explain over the telephone. So we often need to use extra repositories, as explained here:
https://wiki.centos.org/AdditionalRe...s/Repositories

EPEL is very good, but since it is also sponsored by Red Hat, it too leaves out the media codecs! For them, you need something like RPMFusion
https://rpmfusion.org/
But if RPMFusion has its way, it might alter your base installation. You must prevent that, by setting up priorities before you let it install anything:
https://wiki.centos.org/PackageManag...Yum/Priorities
So I have the CentOS repository set to priority=1, EPEL with priority=2, and RPMFusion with priority=3.

The nux-dextop with the EPEL repo enabled would be a lot safer, as they should not overwrite any "base" packages.

You can also use VLC media player, which might be a lot easier for you.

The mpg123 package is in the EPEL repo. And if the OP doesn't want to add the entire EPEL repo, he can download the mpg123 rpm and install it separately per these instructions:

Try 'mpg321', it's almost the same, or you may have 'amp' available.
