Howto Audio

Notes on configuring the sound in Ubuntu

Something I need to look more into yet, but some links to start:

• YoLinux old tutorial on setting up the real audio server
• Using ecasound in DemocracyNow! to setup multiple encodings at once (ogg, mp3, video, etc)

• Thomer's Music Vault custom written in perl for debian

For the times when you need to record from the line out (e.g. audio stream) to a file.

• vsound: for this command line tool, available in Ubuntu packages at least...
  • vsound -d -f output.wav realplay input.rm to listen and record at the same time

• mplayer: from Thomer's howto...
  • mplayer -noframedrop -dumpfile out.rm -dumpstream rtsp:||url/to/file.rm
  • also Matt Paynes blog link

• Audacity: (did NOT seem to work on GNU/Linux. Assumed File→Preferences but could only set input and output to /dev/dsp) from their FAQ on recording streaming it’s as easy as...
  • In the drop-down menu on Audacity’s mixer toolbar, choose “Wave Out” or “Stereo Mix” as the input source. (The exact name may be different, depending on your computer’s sound drivers.) When you press the Record button, Audacity will capture whatever sound is playing on your computer’s speakers.
  • If this doesn’t work on your computer, you can instead use a cable to connect your computer’s “Line Out” (speaker) port to its “Line In” port, and use Audacity to record from Line In.

• oggenc: from the man pages
  • oggenc -b 160 -a “Moby” -l “Hotel” -t “Blue Paper” moby-hotel-blue_paper.wav -t “Swear” moby-hotel-swear.wav -t “Not Sensitive” moby-hotel-not_sensitive.wav -n “%a - %l - %t.ogg”

Ubuntu 79959 - Breezy Sound Howto, kill esd and setup Alsa

Ubuntu 79363 Had same problem, all sound worked (mp3, dvd,) all basic codecs etc. But when playing an audio cd, no sound, no matter what application I tried using (gnome-cd, xmms, cdplay (cdtools), totem etc..). Then I found a solution (partial) here: http://www.eglug.org/node/1644 ... Perhaps because there is no audio cable from the CDROM drive.

For XMMS:

1. Under Preferences, select “I/O plugin”: CD Audio Player 1.2.10 (libcdaudio.so)

2. Press “Configure”.

3. Change the “Play mode” from “Analog” → “Digital”.
