Description Anton Kuleshov 2013-11-09 14:17:30 UTC
Hello. Original: https://bugs.kde.org/show_bug.cgi?id=327341

I have problem with alsa. As i wrote above this happens with knotify when it played back two or more notifications at same time. With Amarok this happens randomly, eg when changing tracks. Other apps crashes are rare and unpredictable.

This is my second report, let me know please if you need more information.

Reproducible: Always

Steps to Reproduce:
1. Trigger a two or more sound notifications at same time.

kernel 3.10.17, alsa-lib 1.0.27.1, sound card - creative x fi titanium.

https://bugs.kde.org/show_bug.cgi?id=327341#c1 says "Please install debugging symbols for all the libraries in thread 2 and report this upstream."

Please do that. See eg. http://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces

And then file upstream ALSA bug and link the bug here.
Comment 4 Anton Kuleshov 2014-08-19 21:20:19 UTC
Thanks for reply. Please tell me where i can file upstream ALSA bug? Bug tracker https://bugtrack.alsa-project.org/alsa-bug not working.
Comment 5 Pacho Ramos gentoo-dev 2015-07-08 13:40:13 UTC
Please retry with 1.0.29

About the bug tracker, bugs should now be sent to their alsa-devel mailing list

thanks
