I've figured out how to play an audio CD from the command line.
I rebuilt a full LFS (today's SVN). I then installed alsa-{libs,utils}.
I ran alsamixer for the volume and the speaker test is fine. It also
plays a .wav file without problem.
I then installed cd-paranoia. It copies files from the audio CD to a
.wav file. aplay plays the .wav file OK.
I then installed libcdio. It has several programs - cd-info,
cd-drive, cd-read, cdda-player. It seems to read the cd ok. For example:
$ cdda-player -l
Title :
Artist:
1: [1379 seconds]
2: [560 seconds]
3: [484 seconds]
4: [793 seconds]
but it doesn't seem to know anything about alsa so it doesn't actually
play anything.
libcdio is mentioned in several places in the book as an external
optional dependency: gvfs, audacious, ffmpeg, mplayer, and
gst-plugins-{good,ugly}.
The last thing I installed tonight was mplayer. After building it, I
didn't see libcdio being used. Perhaps that's because cdio installs the
headers in /usr/include/cdio/ and mplayer is looking for
/usr/include/sys/cdio.h :(
Playing the audio CD sorta worked with mplayer but it stopped and
started in a very irritating manner. I finally got it to work OK with:
mplayer -cache 1000 -ao alsa cdda://2
The 1M cache seemed to do the trick. It can be set permanently in
/etc/mplayer/mplayer.conf or ~/.mplayer/config.
There certainly are a lot of audio apps in BLFS. I'm going to try to
explore them a bit more. There are lots of configuration issues to
check. The command line apps include:
ogg123
mpg123
vlc
pulseaudio
(plus alsa and mplayer)
and the GUIs include
gmplayer
qvlc
amarok
audacious
plus there are a bunch multimedia of libraries.
