Chuck audio and linux alsa
Subject description: Just compiled chuck 'make linux-alsa' and I can run the apps, no error, but no sound either. |

I am running the examples in the source distro, and every one will not give sound. Can I possibly output to a wav file or other format.
I do the following, no sound.

When running normal audio programs like a music program, it is set to alsa mixer and will play.
Am I doing something wrong.
My system is an intel x86,
Linux houston 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 GNU/Linux
Ubuntu Linux (most recent one) |

If you wish to output to a wav file, you can find a "rec.ck" from the examples/basic directory of chuck. The command line would be "chuck stereo_noise.ck ../basic/rec.ck:output.wav" in this case. See also rec-auto.ck.
You said in other music programs you get audio, can you check what alsaplayer --verbose says when playing an audio file? I'm thinking perhaps ChucK writes to wrong Alsa device by default.
If Jack works for you, one option might be to try to compile Jack output. That way you get more flexibility for routing the outputs/inputs to various applications.

I haven't been able to make much progress. I tried the output to wave and just seemed to hang, not do anything, with the command you gave.
I went back to the regular audio and this is what I get. I haven't able to tell what device I am running with, the alsaplayer didn't print much.

Berlin, Could you run "chuck --probe" and post the output here? That should tell us more about how ChucK sees your system with regard to audio in&out (as well as MIDI).
Also; I have no idea of your level of experience with Linux compilation but I should ask as this seems to be a relatively common oversight; could you verify you have the "dev" version of the ALSA library as well as the regular version? For me these are called; "libasound2" and "libasound2-dev" and I run Ubuntu as well. If you lack the "dev" version you'll need to grab that, then recompile ChucK.

Here is the output:

I got libsound2-dev, I will recompile again just to make sure

OK, i tried to change the 'dac' output to device '1', this is the output I get:

Seems like it won't detect the device, but other apps work. |

Berlinbrown, please check that no such programs are running, which could be using the audio system. I know that gives trouble if the program does not want to play nice with others which want to use audio.
E.g. if you're in KDE, quit Amarok and so on.
Also, try -dac2. Maybe you must also specify -adc1 or -adc2.

No dice, I went to the 'ubunut' apt-get install chuck version
And that didn't seem to work either.
I may keep trying though. |
