New Audio Solution Needed

[K2IE]

Current Linux kernels no longer support the /dev/dsp sound device. A new solution is needed to enable sound.

If your distro uses pulseaudio, can't you run "padsp xtrs ..."? I thought I had added a hint to the man page to do that, but apparently I didn't (?!). Or has a kernel change broken that too?

[TimothyPMann]

p.s. Even if padsp still works, it would be good modernize xtrs's sound support, of course.

[K2IE]

This is interesting. When I run padsp xtrs I get:

ERROR: ld.so: object '/usr/lib64/pulseaudio/libpulsedsp.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

I'm using the system provided library package.

This I'm sure has nothing to do with xtrs, but I'm unable to validate whether padsp works because it does not work on my system.

[TimothyPMann]

Maybe you are using a precompiled 32-bit binary of xtrs. What does "file xtrs" report (where xtrs is the path to your xtrs binary)?

[K2IE]

Yes it turned out I was using a 32 bit version I had built for some reason that I do not recall. But when I originally looked at the Makefile, I didn't see any 32 bit directive. After your comment I went back and remembered Makefile.local. Rebuilt as 64 bit and can confirm that on Fedora 33 padsp does provide sound. Thank you @TimothyPMann
