SAPGUI for Java, problem with sound (Linux)

[Former Member]

Hi,

Some time after booting my PC the sound goes off, all applications plays no more sound without any error message.

Finally I took a time for analyzing and I see playing a flash video, the following message from Firefox:

ALSA lib pcm_pulse.c:752:(pulse_prepare) PulseAudio: Unable to create stream: Too large

It's hard to suspect from SAPGUI, but it's the origin of the problem.

I tested these versions:

7.20rev11 (no sound)

7.30rev2  (fine: for each sound opens a sink and client, and closes in 5 seconds)

7.30rev9  (wrong: for each sound opens a sink and client, and remains until sapgui is closed)

7.30rev10 (wrong: like 7.30rev9)

7.40      (wrong: like 7.30rev9)

I have no more revisions for 7.30 installed and I don't see changes in the release notes in between.

The problem starts somewhere in 7.30, which don't close the audio streams and occupies all available even for other programs.

Any of you noticed the problem? maybe with different linux configuration... although mine is pretty standard.

FYI today i received a test version of the SAPGui software compiled yesterday and the problem seems to be resolved.

Sound threads/sinks are closing again after playing the sound like it should be and don't stay open and block the system anymore.

So let's wait for the next rev. and everything should be fine.

Hello Manuel,

apologizes that it took some time, we had a couple of other fixes in the pipeline as well.

I am glad to read, that the issue is solved with our fix.

Best regards

Hi,

it's all good. Sound is not essential for me to work with sapgui so this was not on high priority

I just disable sound output in sapgui until it is fixed...

Thanks for the support and have a nice day!

I have the same problem, on ubuntu 12.04 and others..

I re - instal java and all is Fine.

I have exactly the same problem.

With every sound sap produces there's one more thread in the audio output list of applications.

I use gnome-shell and you can observe the bug in the Audio Settings>Applications.

Can you please add a JavaGUI trace to the thread?

Hello Manuel,

tracing does not really help in this case.

Please create a support message on component BC-FES-JAV.

We already have fixed something regarding sound lately (after rev 1), we would like you to verify with an intermediate version if the issue is solved with that chance.

Best regards
