| + | For most changes to /etc/asound.conf you will need to restart the sound server (ie. sudo /etc/init.d/alsa-utils restart) for the changes to take effect. | ||

| + | === Early Observations === | ||
| + | The stock asound.conf file looks like: | ||
| + | <pre> | ||
| + | pcm.mmap0 { | ||
| + | type mmap_emul; | ||
| + | slave { | ||
| + | pcm "hw:0,0"; | ||
| + | } | ||
| + | } | ||
| + | |||
| + | pcm.!default { | ||
| + | type plug; | ||
| + | slave { | ||
| + | pcm mmap0; | ||
| + | } | ||
| + | } | ||
| + | </pre> | ||
| + | ... the problem here appears to be that a 'plug' channel (?) is assigned by default, however, [[jack]] is not installed. Bummer! Causes many of the players to fail. | ||
