I have DXR3 card with ADV7170. I have quite bad audio sync problems with it and was wondering if there is some fw which is better over others. The problem is that I must every once and a while pause replay for a second or so or when watching live TV change the channel back and forthto get the sync back. I.e. I have a timer that causes vdr to start every morning to record the morning show which I start to playback as soon as I get up. During the next hour or so I must use pause at least five time or more. This happens every morning.
I have: vdr (1.4.6-1/1.4.5) - The Video Disk Recorder dxr3 (0.2.7) - Hardware MPEG decoder
and in case it matters burn (0.1.0-pre21) - Versatile convert-and-burn plugin dvd (0.3.6-b03) - turn VDR into an (almost) full featured DVD player wapd (0.8) - Remote control by WAP ttxtsubs (0.0.5-RRE) - Teletext subtitles text2skin (1.1-cvs) - Loader for text-based skins subtitles (0.5.0) - DVB subtitles decoder epgsearch (0.9.22) - search the EPG for repeats and more osdteletext (0.5.1) - Displays teletext on the OSD mp3 (0.10.0) - A versatile audio player mplayer (0.10.0) - Media replay via MPlayer quickepgsearch (0.0.1) - Quick search for broadcasts femon (1.1.3) - DVB Signal Information Monitor (OSD) vompserver (0.2.6) - VDR on MVP plugin by Chris Tallon epgsearchonly (0.0.1) - Direct access to epgsearch's search menu conflictcheckonly (0.0.1) - Direct access to epgsearch's conflict check menu
thanks in advance \Kartsa

Hard to say, I think I tried the only 2 fw revisions I know of and I don't remember any difference. I'm currently using version 0x29 (at least that's what I see in /var/log/messages, see below) and I don't have any apparent audio sync problem.
kernel: adv717x.o: Configuring for PAL kernel: em8300_audio.o: Analog audio enabled kernel: em8300: Microcode version 0x29 loaded kernel: adv717x.o: Configuring for PAL kernel: em8300_audio.o: Analog audio enabled
Bye

Me too.

It's been some time, but IIRC I've tried all that I could find, and the 0x29 one that comes with the drivers has worked best for me.
The problem is that I must every once and a while pause replay for a second or so or when watching live TV change the channel back and forthto get the sync back.
Same here, but not often enough for it to really annoy that much. I think it happens mostly for MTV3 here.

I've tried a couple also and the funny thing is that they all reported 0x29 in log even though diff said they are different.

I have been wondering if the reason could be MTV3 but I thought it could not depend on it. I must try to use some YLE channel for my morning recordings.

If you're using WSS you could try turning that off when testing. Changing WSS mode the way it is implemented in the driver currently makes the picture "jump" a little and from what I've observed this causes the video to stop but audio keeps going. Obviously a single jump will only desync it for some milliseconds, not enough to really notice and definitely not enough to be annoyed by it.
MTV3 likes to switch the mode a lot, though. And by a lot I mean between every single commercial they reset to 4:3. This happens even when it is not needed and will just be set back to 16:9 by the next one.

I did try recording TV1 instead of MTV3 and guess what, no sync problems what so ever. But the problem seems to be on MTV3 even if there is no commercial (this one I must still check more thorough). And the out of sync becomes easily to about 1 second which is REALLY anoying. Its like watching some asian movie with dubbed sound. I have not tried disabling wss and that would not be my first choise since I deliberately looked up an ADV7170 card because of its wss ability.
