libasound is mandatory for startup on Linux

[baget]

when trying to run on latest WSL with Ubuntu, getting the following error:
sampler: error while loading shared libraries: libasound.so.2: cannot open shared object file: No such file or directory

[sqshq]

1.0.1 was released, the fix for this issue included. Could you please update Sampler and try again?

sudo wget https://github.com/sqshq/sampler/releases/download/v1.0.1/sampler-1.0.1-linux-amd64 -O /usr/local/bin/sampler

didn't work
why does the sampler need libasound?

[baget]

I'm using it on my personal Windows 10 (1903) computer, you can use VM to test it

Was able do reproduce. Can be fixed with apt-get install libasound2, but it better work without it. I'll see what I can do.

The libasound is needed to play a beep sound (NASA quindar tone) on conditional action (trigger): https://github.com/sqshq/sampler#triggers

that solved the issue, maybe you should add it to the README?

[sqshq]

Done.

Struggling to solve this dependency on RedHat. Is it possible to make it optional?

[sqshq]

Yes, that's the plan. I'll try to figure out how to do that without removing sound tone functionality completely. Right now the binary needs to dynamically load libasound at runtime, that's why we are failing on startup.

Any ideas are welcome.

Oto player also causes me troubles with cross-compilation for ARM.
Need to do something with it.

I ran into the same issue on a system I am not the admin of. To have an option to disable the sound feature altogether would be handy.

Wrote a small wrapper script that sets the LD_LIBRARY_PATH to include the directory that the sampler binary is located in and copied over the libasound.so.2 from another linux system. Then at least I can run sampler.

Didn't test using a trigger to get a sound, I assume it would break as the lib file by itself might not be enough for it to work...

sampler.sh :

#!/bin/sh

if [ -n "$LD_LIBRARY_PATH" ]; then
  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./
else
  LD_LIBRARY_PATH=./
fi
export LD_LIBRARY_PATH
exec ./sampler-1.0.2-linux-amd64 "$@"
