Here's my test case: I launch audio_play and audio_capture in separate terminals. All works fine but when I terminate audio_capture and restart it, just silence is delivered.

The same problem occurs when playing the /audio topic from a bag file.
The problem doesn't occur when I use a file sink instead the alsasink.

The gstreamer log says nothing except

0:02:59.233072514 17796 0x7faecc04e120 WARN                   pulse pulsesink.c:651:gst_pulsering_stream_underflow_cb:<sink-actual-sink-pulse> Got underflow

when I terminate audio_capture. When I restart audio_capture the log says nothing on the info level. On the debug level it is still very verbose. I can't see a difference between the debug logs when it's working and when not. In the debug log there are messages from the source, the decoder, the converter and the sink.

The onAudio callback gets called as it should be and g_signal_emit_by_name returns successful.
I also checked that the pipeline is in PLAYING state all the time.

I checked this problem on two different machines with Ubuntu 14.04 and Indigo.

As this doesn't appear with a file sink I suspect either the decoder, converter or the sink. Does anyone have an idea how to fix this or how to further debug this?

Edit: The gstreamer graph is identical in both cases. I plotted them with GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS().

Hi,
whenever I try to play a sound or say text, the sound node generates this error and introduces a delay in playing:

screen readers for the blind, which need to run.

From experience, the soundplay_node crashes after running for an extended period of time.

Poking at it a bit more, it appears to be leaking open file descriptors, and when it hits the OS limit of 1024 open file descriptors, it's unable to create or play sounds and crashes.

Having an actionlib or actionlib-like library for sound playback would be good. See http://answers.ros.org/question/11281/sound_play-action-library/

Could you please describe the format of the data field in the messages created by an audio_capture node (audio_common_msgs/AudioData)?

From what I could tell, the output is written from a gst.Buffer with entries of type signed long. However, this is strange because the number of bytes of the data field is sometimes odd, when is should be a multiple of 4 (the size of a long).

In the end, I need to obtain the audio data with respect to time from rosbags of the output of an audio_capture node.

Please release this module for the upcoming ros distribution indigo.

It compiles/runs fine with indigo, although I would propose to rename sound_play's "test" binary. This target name officially reserved by cmake and cmake warns about it.

(I came across this while working on #64, personally I have no use for this functionality but I figured it would be good to report).

The SoundClient's repeat() method does not appear to actually repeat the sound (instead it just plays it one time).

MWE:

def play_repeat():
    soundhandle = SoundClient()
    rospy.sleep(0.5)

    sound_beep = soundhandle.waveSound("say-beep.wav")
    sound_beep.play()
    rospy.sleep(1)
    sound_beep.repeat()
    rospy.sleep(5)

The first call plays the sound once, as expected.

The second call is expected to play the sound "repeatedly until stop() is called," but it also only plays it one time.

Tested on Ubuntu 14.04 with ros indigo.

I need to confirm that audio_common builds and installs properly on Hydro, and then release HEAD as 0.2.5

the sound_play node is missing a rosdep on python-gst0.10, so it doesn't pull in the proper dependencies on new ros installs.

This is blocking shipping new PR2s with Electric. Please fix.

There is currently no Jade Debian package yet. It would be great if we could simply bump the gbp release and rollout the nice new package. Right now, I am compiling it from scratch to use it with Jade.

And then I will fix this:

We faced troubles during building this stack for the Raspberry Pi.
During catkin_make an error on the dependencies in CMakeLists.txt occurs.
We could solve this issue by removing line 18 in CMakeLists.txt (add_dependencies(audio_play, ........).
Is this a bug?

Is there an easy way to use audio_capture to record bag files from multiple microphones?

Hi,
Some codes to call sound_play to play a wav file that i have writen are:
sound_play::SoundClient sc;
const char *str2 = "/home/turtlebot/Desktop/ros/Welcome.wav";
sc.startWave(str2);

then run the codes, the error is :

what should i do? How to change the version of robotsound?

According to ROS Indigo - the line should be:

self.pub = rospy.Publisher('robotsound', SoundRequest, queue_size=1)

If a user is logged in, then only that user and sometimes root can play audio. For sound_play on robots, sometimes we have a GUI user that logs in, but other users or scripts play noises from the background.

I tested this on Ubuntu 12.04 64 bit with Fuerte.

Maybe forgot to close file descriptor after playing audio file?

The sound_play package is missing a dependency on actionlib, only actionlib_msgs are defined in package.xml.

This causes build breakage for any code using SoundClient() on a clean machine, for example here:
https://travis-ci.org/felixduvallet/audio_common/builds/92227443

As reported in detail in the QA thread ( http://answers.ros.org/question/3212/sound_play-consumes-high-cpu-and-makes-strange), soundplay_node.py instance doesn't stop increasing under certain circumstance and consume significant amount of CPU which makes it hard to keep running everything on the same computer.

Hi,

I would like to report that while following the tutorial steps for audio_common, ( http://www.ros.org/wiki/audio_common/Tutorials/Streaming%20audio ) , at the step for installing the ROS dependencies I encounter the error:

shanker@StudioXPSubuntu:~/Workspace/Aux-ROS-Packages/audio_common$ rosdep install audio_common
Failed to find rosdep gstreamer for package sound_play on OS:ubuntu version:10.04

Failed to find rosdep gstreamer for package audio_play on OS:ubuntu version:10.04
ERROR: ABORTING: Rosdeps [u'gstreamer', u'festival', u'gstreamer', u'gstreamer'] could not be resolved

I suppose the solution would be to ignore that and install these packages from Synaptic Package Manager for example. I have done so and installed 'libgstreamer0.10', 'libgstreamer0.10-dev', 'libgstreamermm-0.10-dev' and 'festival' from Synaptic Package Manager.

I then followed the rest of the tutorial, and at the step "Testing your setup" upon execution of the command 'gst-launch-0.10 alsasrc ! audioconvert ! audioresample ! alsasink', I do hear my input being played back to me, with a little delay.

However, at the final step of using audio_capture and audio_play, I do not hear any output. I would also like to note that I have also recorded a bag file while running audio_capture, and the bag file did not have any data under the /audio topic.

I wonder if the problem is with the aforementioned 'rosdep' issue, and that I have installed an incorrect dependency. On the other hand, could it be that I am using a Macbook and the soundcard in question is not handled by audio_capture?

Thank you,
Regards,

While the documentation of the sound_play node says that more than one sound at a time can be played, this appears not to be the case (even when calling it from the same node).

Lines 181-182 of soundplay_node.py are "Force only one sound at a time" and "self.stopall()". Commenting out the latter seems to allow multiple sounds to be played at once.

Either the documentation or the code should probably be changed, however, I have not experimented significantly to determine whether commenting out line 182 of soundplay_node.py leads to undesirable effects.

The hydro package of sound_play does not include the header file. The CMake file lacks a proper install rule like this:

(as mentioned on http://answers.ros.org/question/100941/sound_playh-not-in-included-in-ros-hydro-sound-play/)

For the 'say' command, soundplay_node.py creates a couple of files in /tmp, i.e. play_sound_text_temp.txt and play_sound_wave_temp.wav, but doesn't set their permissions to be non-owner writable.
