We have an Allstar node and added DMR link to it and then added IRLP to that node. Here is a link that will give you directions. If you need any help reach out. https://docs.google.com/document/d/1eN50Csr29eAprBu7eKA0Bfa2XUcsXw5iktY1Ey-Qjkg/edit ----------------------------------------------------- How to send PCM directly to your sound card and thus to your speaker: From: https://unix.stackexchange.com/questions/13732/generating-random-noise-for-fun-in-dev-snd You normally can't write audio using /dev/dsp anymore, at least without being tricky. There is a program that will accomplish this for you on your system: padsp. This will map the /dev/audio or /dev/dsp file to the new Audio Server system. Fire up the terminal and get into root mode with sudo su. Then, I'm going to cat /dev/urandom and pipe the output into padsp and use the tee command to send the data to /dev/audio. You'll get a ton of garbage in your terminal, so you may want to redirect to /dev/null. Once you're in superuser, try this command: cat /dev/urandom | padsp tee /dev/audio > /dev/null You may even want to try with other devices, like your mouse: Use: /dev/psaux, for instance or the usb driver. You can even run your memory through it: /dev/mem -------------------------------------- Try /dev/audio or one of the other devices under /dev/snd. Not all of them are audio data sinks, you might have caught a mixer, microphone, or something ---------------------------------------- cat /dev/urandom | padsp tee | aplay is the command that needs to be typed. If you aren't in "audio" group, you could prefix aplay with sudo. This also doesn't interfere with any daemons (I was running pulseaudio while this command was active and correctly heard the "noise". ----------------------------------------- Is a sound daemon (e.g. pulseaudio) holding a lock on the device? I think you can find out if anything else has a handle on it via lsof. Thanks for the helpful suggestion. I had a check, using grep and lsof. pulseaudio is using /dev/snd/controlC0 but it isn't on /dev/snd/pcmC0D0p . I had a double check by going to /var/lock to find if there was a file for a lock on the device. ls -al tells that the folder is empty. So I guess there is no lock on pcmC0D0p -------------------------------------------
