Problems with sound in lmms

English Hardware
#1

Hello, I can produce sounds in many applications like banshee, etc. The problem I have is with lmms. It doesn’t sound at all. I get the error:

ALSA lib pcm.c:2211:(snd_pcm_open_noupdate) Unknown PCM /dev/snd
Playback open error: No existe el fichero o el directorio
No audio-driver working - falling back to dummy-audio-driver
You can render your songs and listen to the output files…
Couldn’t create MIDI-client, neither with ALSA nor with OSS. Will use dummy-MIDI-client.

Does anybody know how to overcome this problem?

Given sound works in your other applications, this is most likely an issue with lmms’s configuration putting sound out through your second sound device. Connect your speakers to them and see if the second audio device is giving you sound …

You could also look at the lmms troubleshooting page for hints: Troubleshooting - LMMS-Wiki

For example this linkwhile addressing pulse audio introduced lag, refers to multiple sound devices and provides a hint as to how one can deal with such a situation.
