(1) Do you have the necessary codecs installed: libvorbis for .ogg and libmp3lame for .mp3? The Sparky Linux Codec package has both. I presume your player is also properly equipped. Also presume you didn't get playback recording mp3.
(2) You can try substituting "pulse" for "alsa" in the commands, but unlikely to help.
(3) Did you upgrade your "ffmpeg", that is, getting the latest version of
ffmpeg and
ffprobe from
http://ffmpeg.gusari.org/static/64bit/ as I suggested in the text of the article?
(4) "i" is "input device", and depends upon many things and can be changed to accommodate what you want to record down to the input to a single speaker in a multi-speaker system, for example, with a 7-way external speaker system. The "catch-all" is to just enter "default", and it will usually work. To see what audio devices are on your computer, put
aplay -l into your terminal. Mine looks like the following:
Code: Select all
me@me-N76VJ:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC663 Analog [ALC663 Analog]

Subdevice #0: subdevice #0

card 2: S51 [SB X-Fi Surround 5.1], device 1: USB Audio [USB Audio #1]
Subdevices: 1/1
Subdevice #0: subdevice #0
From this information, there are 2
levels of input possible (in place of "-i default"). They are "-i hw:[card#]" or "-i hw:[card#,device#]". So in my computer with the "aplay -l" output above, all the following would be proper (but not necessarily productive): "-i hw:0"; "-i hw:2"; "-i hw:0,0"; "-i hw:0,1"; "-i hw:2,0"; "-i hw:2,1" . I suppose the computer hardware and installed audio software determine which and how these designations work. Even worse, these can change with a reboot, so they are not really that useful for a general script.
To get even more refined audio information about your computer and designations that are not suppose to change with every boot-up (unless you change the hardware), put "arecord -L" into your terminal. Here is the first few lines of mine (over 100 lines total which means like 50+ recording possibilities):
Code: Select all
me@me-N76VJ:~$ arecord -L
default
Playback/recording through the PulseAudio sound server
null
.....
So, "default" is "Playback/recording through the PulseAudio sound server". Do you have "pulseaudio" installed? It appears "-i default" is the most sensible way to go. I have tried recording with many of these different settings, and the one that ALWAYS sounds closest to the original by my ears has been "-i default". So, no point in arguing with a simple solution when it is also the best solution.
