Note audio output works on TV playback but not sure if my audio setup is correct I'm using ALSA:Default

please provide a backtrace, there's no crash here..

comment:3 Changed 9 years ago by Paul <paul@…>

I've install the debug-info rpm but I still don't get a backtrace but I see this in my kernel log

mythbox kernel: mythfrontend[26318]: segfault at 139214 ip 07e9798e sp a32fa0d0 error 7 in libGL.so.260.19.12[7e13000+a8000] mythbox kernel: mythfrontend[26458]: segfault at 139214 ip 07e9798e sp a30170d0 error 7 in libGL.so.260.19.12[7e13000+a8000]

When I click the Scan for Audio devices the Frontend closes.. so I'm guessing thats not normal , or is it?

I'll try to get some more debug info but I'm running atrpms so I'll need to ask the list how to get that working..

Resolution: Invalid
Status: newclosed

Don't see any bugs here nor a crash. When scanning for audio devices, myth go through all the devices reported by ALSA and try to open them; some of them may not be in a working state and will not be added to the list.

If the crash is in OpenGL, update your video drivers.

ATrpms debuginfo packages can be installed with

yum install --enablerepo=atrpms-debuginfo <name-of-main-package>-debuginfo

Re-open the bug if you have a valid backtrace, and have updated to the latest version of your opengl driver (if nvidia, latest drivers are 260.19.21)

For what it's worth, 256.x was also crashing for me.
