Nice. I've ordered one. AX25 is pretty quiet round where I am, except for the occasional APRS chirp.

Re: Basic graphing module/idea help

It might be overkill, but matplotlib is used everywhere for this. Alternatively (and even more mature) you could pipe the data to gnuplot.

Re: Which sound system for reliable Python audio?

Update: I switched to pulseaudio, and it works fine. Details: A Murder of Crows on your Raspberry Pi with Boodler.

I'm effectively running 09/02/2013 through dist-upgrade and rpi-update. pulseaudio works fine, so I'll stick with that. Thank you!

Thanks, but I'm still getting lockups. I appear to be having the same problems as Bill in his thread Sound problem - aplay lock up . I'm running from the console. X is not running.

Try:

Code: Select all

arecord -f cd -d 5 -D plughw:1,0 test.wav
Your first attempt was 8kHz mono 8-bit, which doesn't sound great.

Re: alsamixer problem

Do you really need to use sudo? By running it that way, you might be setting the ALSA configuration for the root user, not the regular user.

Which sound system for reliable Python audio?

I'm trying to run Boodler on the Raspberry Pi. It's an open source “soundscape” tool that generates ambient effects. It needs to be able to talk to a sound system, but in Linux (Raspbian), there are so many to choose from, including OSS, Alsa, Esound, and Pulse. Is there one "this'll just work" soun...

It's seen by my elderly Roku SoundBridges and other DAAP clients. DAAP appears to be dead in iTunes 11, so — unsurprisingly — it doesn't show up there. I've ha...
