Hi, I have found a glitch in the saa7146 when booting from cold. I'm not entirely sure how to fix it. It affects the budget and budget-ci cards I have tested, so it may affect others. Test: 1) unplug a machine for 30 seconds 2) boot it up 3) run dvbtraffic 4) tune to a valid frequency (and ensure it _only_ tunes and does not open the demux again) Step 4 will lock fine, but dvbtraffic will never see any data. To fix the problem, you have to start+stop dvbtraffic (i.e. close+open the demux). After that, _everything_ works as normal; the same test can now be repeated, and dvbtraffic will get data finie. This also only affects cold boots; warm boots are fine. Testing with debug on shows that when step 4 above locks, the saa7146 simply stops sending VPE interrupts. Closing+reopening the demux causes the SAA7146 ts stream receive configuration to be reconfigured and that seems to fix the problem. Simply initialising the frontend and/or tuning to an invalid frequency is not enough; I have to tune to a valid frequency and wait till it locks before I can guarantee everything works correctly. Note: if I tune, and then open the demux _before_ it has completely locked on a cold boot, I see this same issue. Anyone have any ideas? I've not tried a budget-av card yet, but I have a suspicion they may be affected as well. _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
