Arch Linux

Package:

extra/hydrogen 0.9.3-6

Issue:

Having JACK as the output driver will not work by default. This is because the global configuration file hydrogen.default.conf (which writes the user's one on first run) does not reflect JACK's new port naming scheme. Hydrogen will not be able to use the server for any purpose, and will not output much relevant information.

The issue can be found when looking at the server's verbose messages, relating to unrecognized ports. Even if it is an upstream bug, the solution is rather simple. If however the fix is not implemented by the next upgrade, the user's configuration file may get overwritten.

It has been claimed that since jack-audio-connection-kit 0.109.0 the server has a workaround for application's using the older "alsa_pcm" scheme. However, that does not appear to be true and it has to be manually changed to "system".

Fix:

sed -i 's:alsa_pcm:system:g' $pkgdir/usr/share/hydrogen/data/hydrogen.default.conf
sed -i 's:outs>false:outs>true:g' $pkgdir/usr/share/hydrogen/data/hydrogen.default.conf
