RE: [ALUG] Audio problems
From: Martin Collins Sent: 24 October 2006 20:19
I'm using Ubuntu Dapper on my laptop with kernel 2.6.15-27-k7. There's a problem when playing DVD's or video files with the lip-sync. The audio is 200-400 ms ahead of the video. I've googled for answers but just can't seem to find any. This wasn't a problem before I installed Dapper, but I don't want to uninstall it because of one annoying little problem.
I know it's the computer and not the files because I've seem them played on Windows machines with full lip-sync. Has anyone experienced any problem like this, or should it be reported to Ubuntu as a bug?
Its an nforce3 audio chip (0000:00:06.0 Multimedia audio controller: nVidia Corporation nForce3 Audio (rev a2))
Thanks all,
Martin
Have you tried installing the EasyUbuntu upgrades? (http://easyubuntu.freecontrib.org/) Fixed a similar problem on my desktop system. Regards, Keith ____________ FUNDAMENTALIST, n.

Hi Martin Same chipset here, but no problems with Kubuntu Dapper 64, Had to give up on Etch, however, because audio was always behind the Video and the frame rate was low, on all players including Mplayer. All usual things, dma,etc enabled. Would like a "cure" as I would like to return to Etch Kind Regards - Nick Daniels
Hi Nick! You pressed the wrong button somewhere - this should go to Martin? My op tomorrow - will be out of action till Wednesday Cheers! Roy On Wednesday 25 October 2006 11:55, Nick Daniels wrote:

Check the earth strap between engine and chassis. Try a dab of grease on the bendix gear. It sounds very much like worn brushes in the starter motor, so checking them is also an option... But paying someone 350 quid to do a head gasket is outrageous unless it is an Aston Martin.. Regards, Paul.

Thanks for all the replies, sorry for delay, haven't been able to check e-mail for a couple of days. I can't perform any updates at the moment as I have no broadband and can only connect via bluetooth and my mobile phone. Long, long, long, long story involving TalkTalk, Tiscali, OFCOM & BT. In short, my tag is no longer on my line and it's clear for other broadband suppliers. However when BT Wholesale (and other broadband suppliers) try to do a test order it throws it back because of a problem with BT's database that BT are trying to fix (for some months now). In the meantime the only way round it is to try and find a broadband supplier that is prepared to do a "manual order". The only one I've found so far is Demon Internet so it looks like I'll be going with them. BT have really annoyed me though. Anyway, after several hours mucking about I've fixed the audio sync problem by switching the audio output in MPlayer to OSS instead of ALSA. All is fine but the only thing that bugs me about it is that I was under the impression that on my Ubuntu 6.06 box, OSS is actually emulated OSS support under, err ALSA. So really whether MPlayer is set to OSS or ALSA it's actually ALSA doing the work. Am I wrong? It works so I'm not going to get too stressed about it but you are right an update should hopefully sort it out. Thanks all. Martin On Wed, 2006-10-25 at 16:10 +0100, Nick Daniels wrote:

Heh all sounds too familiar to me. Is this the problem with BT's database where it can take up to 2 weeks for changes to be reflected (new lines etc) or a different problem.

Hmm that is a little odd, I would have expected the opposite to be true, ALSA experience changes depending on your hardware, In the end I got fed up with various glitches involving software grabbing my audio hardware etc and fitted a SB Live card with hardware mixing support, now I have no problems with sound whatsoever and the quality is noticeably better than the integrated stuff as well. The only slight issue is that my SB card doesn't support front audio sockets so I need to get busy with the soldering iron to get back the functionality where plugging in a set of headphones mutes the rear outputs.

Me too! It took 3 weeks to get a phone line (at least two engineer errors, AFAICT) and then another week and a half to get DSL, as BT Openreach somehow forgot it was a simultaneous phone+DSL order, then rejected the first attempt at ordering DSL because the phone line order wasn't marked as completed on their system. I suspect The Phone Coop might try too, but they're also at the mercy of BT.

Strange. Do you have any ALSA plugins running by default that don't run for the OSS emulation? (aplay -L should give a lot of info, from which you can compare the default and dsp blocks.) Does pointing mplayer at ALSA device hw:0,0 work any better? If not, it might be some version problem between mplayer and libasound or libasound and the kernel driver, but now I'm really guessing.

Hi Nick It was my "Nick" filter wrongly set! I have a kmail filter to send your messages into a folder with your name which put the ALUG messages in too (the ones with "Nick" in sender field.). Sorry about that. Brain a bit fuzzy at the moment. Operation went OK (complications meant overnight stay) and I am back at work doing sit down jobs. Still on painkillers. Sit down jobs include extracting my email from 643 items of spam. I now have a javascript email button to put on my website. It might help a bit.
You pressed the wrong button somewhere - this should go to Martin?
Car problems? Needs more mileage? How about this? Put message on some website where Google can find it "Park your car outside my house and will run you into Stansted airport also pickup when you flyback - only £15 per day" Or something like that. Lots of people doing it.

I have a little problem you might know about. Suse 9.3 box sometimes (every week or so when it feels like it) shuts itself down all by itself for no good reason. It does it gracefully showing all the screens you would expect if you had clicked the "turn off computer" button. This box normally runs all day every working day and for long periods without any human input. I use it to collect email etc. Any idea what is going on? Is there a log I can look at? Cheers Roy
