--- Comment #6 from Mauro Carvalho Chehab <mchehab+sams...@kernel.org> --- (In reply to Wabi from comment #5) > My replies: > 1) Jams of sound and picture of tv programs continous by about 7 seconds > every 15 seconds Kaffeine sets a Kernel buffer in order to store the data received from the TV card. It creates internally a thread that reads from the buffer. Such thread should be able to fully read the buffer before the next one arrives, as otherside packets will be lost. From your description, I suspect that this is what's happening: something is causing the Kaffeine's thread to be scheduled to wake too late. That could happen on some situations: - the GPU driver is taking a very long time to display the video; - the CPU load is too high; - the kernel you're using is on voluntary mode (it was compiled with preemption is disabled) and some task is holding the CPU for a very long time. > 2) Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller, > TechnoTrend AG TT-TVStick CT2-4400, Intel(R) Pentium(R) CPU G3260 @ 3.30GHz > 3) I don't know when I can get it > 4) I don't know when I can get it Without logs, we can only guess the cause of the jams.

I suspect that, on Ubuntu, both "profiles" use X11. I've no idea what your "Ubuntu" profile actually means, but clearly it is doing something bad. Perhaps this "Ubuntu" profile is loading an userspace video driver that doesn't do video acceleration, or perhaps it is starting a process that is keeping the CPU under a very high load. Do you know if it uses X11 or Wayland? -- You are receiving this mail because: You are watching all bug changes.
