I am new to kdenlive. Installed v 0.9.2 on an OpenSUSE 11.4 / ALSA yesterday, and did not manage to get any audio output so far.
I can produce sound from other apps (firefox, audacity, mpg123, ...) but succeeded neither from melt nor kdenlive.
In kdenlive I got some messages at first that no audio device could be opened but I managed to get rid of those. Now, I do see some display in the level meters and the spectral audio analyzer, but still do not hear anything. Interestingly, sometimes I see these messages several times when playing a clip with audio (reported by others to be seen related to crashes, but my kdenlive has not crashed so far):
ALSA lib pcm.c:7316:(snd_pcm_recover) underrun occurred
But: this seems not to occur every time I play clips with audio -- at least once these messages had not been thrown.
In case that clarifies something (not for me though): I do have a file /etc/alsa-pulse.conf containing
There's no /etc/asound.conf and no .asoundrc in my home dir but I got /etc/asound-pulse.conf:
# PulseAudio plugin configuration
# Let's create a virtual device "pulse" for mixer and PCM
# Let's make it the default!
I am not very skilled on Linux sound, so I am not sure whether the above config is somehow invoking PulseAudio -- I do start just the alsasound init.d script so my guess is I am using ALSA ...
If someone has some advice or suggestions how to fix my issue I'd be grateful.
UPDATE: The message that no audio device is avail ("SDL failed to open audio: No available audio device") is seen always when i had kdenlive off, restart alsa (service alsasound restart), start kdenlive and play a video. If I confirm that error message, it does not return, even not after shutting down and restarting kdenlive. It requires in addition the alsa been restarted to recur.
