Ok, I found the bug, I attached the solutive patch. With this patch, xoscope could be invoked with aoss or padsp without errors.
Problem araises when ioctl value is passed on 64 bit via a signed integer in method check_status_ioctl in sc_linux.c . I found what I think could be a second bug, xoscope is not compiled with esound support. There is a bug on the stock Ubuntu oneiric that prevents major esound compatibility (https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/864071) and also after upgrading the package to oneiric-proposed, xoscope could not work with esound compatibility. So I recompiled the ubuntu package (from apt-get source xoscope) enabling esound (it suffices to install the esound libesd0-dev package) and ensured that the proper configure flags was set. After the recopilation process finished, I installed the package and it worked! So I think the package should be recompiled with esound support (so setting the HAVE_LIBESD flag). ** Patch added: "uiioctl.patch" https://bugs.launchpad.net/ubuntu/+source/xoscope/+bug/881695/+attachment/2582141/+files/uiioctl.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/881695 Title: Xoscope doesn't work on soundcard (No valid data sources found... exiting) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xoscope/+bug/881695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
