Hi everybody,
I'm trying to run my rather complex Pd patch on an Up Board (x5-Z8350 CPU,32GB eMMC, 4GB RAM). The board has the RPi formfactor but is much more powerful.
The up board comes with ubilinux (64bit debian version especially for the Up Board). After spending a lot of time with ubilinux and the normal debian9.1 (64bit) I couldn't stop it from constantly crashing when I opened my patch - for some unknown reason.
it would be interesting to know why that is happening. e.g. by producing a stacktrace via gdb. (from a dev perspective i find this a much more interesting problem to solve than "why is my ALSA not working")
After giving up with the 64bit OS I installed debian 9.1 (32bit) and it's running perfectly stable as before with my old amd hardware. No more crashes!
amd hardware? what happened to the up-board?
All externals (except for "iemlib/mp3play~"
what's wrong with mp3play~?
and "toxy/tot" [not to be found anymore]) are working as expected. However, with the normal debian alsa is NOT giving me any sound!
Then I compiled the kernel with oss but oss is not producing any sound either.
did you try jack?
Here is what I get from pd when turn on alsa:
ALSA input error (snd_pcm_open): No such file or directory ALSA output error (snd_pcm_open): No such file or directory
The (external USB-)sound card does show up in the drop down menu of Pd's audio settings for selection, though. So it is regognized both by pd and the operating system. I tried several different USB sound cards with the same result.
Here is what I get when I try to open alsamixer from the LXTerminal:
error when opening mixer: No such file or directory (original in German: Fehler beim �ffnen des Mixer-Ger�tes: Datei oder Verzeichnis nicht gefunden)
When I use portaudio I'm actually getting sound but it is very quiet as the sound output is turned down by the system during start up. I can't find any way to turn the volume of the sound card up, though since I cannot open any mixer.
Does anybody have an idea how I can get alsa to work? Debian tells me that "alsa-utils" and "alsa-base" is already installed with the newest version (1.1.3-1 and 1.0.27+1).
*alsa-base*? Debian>=9 doesn't ship an alsa-base package any more. how did you install it? do you by chance mix some (incompatible) repositories?
what's the output of aplay -l
