errors on launch soundplay_node [closed]
I got some problems using the soundplay_node of the sound_drivers stack.
First of all: My speakers are Logitech USB speakers and are connected, activated, not muted, volume is adjusted, no red LED and THEY ARE WORKING. I used aplay to play some .wav files and I also successfully used the mpg123-player to listen to .mp3 tracks.
When I startup with
roslaunch sound_play soundplay_node.launch
I always get this error message:
[ERROR] [WallTime: 1315304498.071437] Exception in sound startup, will retry once per second. Is the speaker connected? Have you configured ALSA? Can aplay play sound? See the wiki if there is a red light on the Logitech speaker. Have a look at http://pr.willowgarage.com/wiki/sound_play/Troubleshooting Error message: No available audio device
If I start in an extra terminal
rosrun sound_play say.py "hello world"
no errors occur but you can't hear anything.
The message is
Saying: hello world
and it is exiting normally.
I tried a lot of things I found in the world wide web but nothing helped. I did the troubleshoot more than 10 times but nothing helped. I read everything about alsa and how to configure. I configured alsa that it uses the correct device (device 1). Here you can see my /etc/asound.conf (I tried a lot with these parameters perhaps I made some mistakes...):

I configured the asound.conf file directly. Before this I edited the ~/.asoundrc-file but without success.
Can you help me get the sound output work?
