How can I set up ALSA on VDS?

Question

Greetings to everyone.

I'm trying to convert SWF to MP4 using dump-gnash and ffmpeg.

But the problem is the dump-gnash won't create raw video without ALSA set up properly.

Here is a part of dump-gnash log:

ALSA lib confmisc.c:768:(parse_card) cannot find card '0' ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name ALSA lib conf.c:4241:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:4720:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default Killed

I readed about ALSA and learned is't a sound card handler tool.

But I don't have any sound cards on my VDS. Then there is a question: how can i set up ALSA on VDS and make it work?

Answer 1

Tell your program to use the ALSA device named null.

If that does not work, try loading the snd-dummy driver.
