You might also want to try the 0.4.6 prerelease - http://www.gossamer-threads.com/lists/ivtv/devel/30420

I've got the lastest version of that working, but I'm not sure if some artifacts I'm seeing are due to the changes or momentary noise in the signal.

Hello, I feel I'm in the same boat as a few others here, so I figured I'd post my findings so far. I'm using R5C7 (fresh install just now) and my PVR-150 won't find any channels during the channel scan, and if I tell it to load the channel data from the listings it pulled from the internet site, I get my channels, but they're all static and no sound either. Hope we can get this figured out soon!

Hi tjc,
Some supplemental information,
I installed the 150 card into my R5C7 machine whiched was working with pvr-350 (removed 350, installed 150 -single card)
At the login box, alt x for a term and looked at dmesg..

Appears nothing likes this bad toy so far.

However, there is more..
I installed the 350 card into the Dell, dumped the card settings, and re-added. Rebooted and when it came up tv was just noise. I did a force to type 50 and rebooted. Mean time I had added a listing for the wife and decided to update the database. Being curious, I selected 68 and I had tv. Further testing brought me the following results.
channels 2-7 black (incrementing)
channels 2-6 black (decrementing)
channels 8-59 snow & lines
channels 60,61 look and sound good
channel 68 look and sound good but with some stuttering, digitizing probably signal quality and 400mhz cpu doesn't help

On that second reboot, dmesg reported tuner type 2 but I had forced it to type 50. Put it back into auto detect and rebooted.

part of ivtv:
tuner: type set to 2 (Philips NTSC (FI1236,FM1236 and compatibles)) by ivtv i2c driver #0
ivtv0: Initialized WinTV PVR 350, card #0

The pvr-350 tuner works fine and tunes all my listed channels on the Dell OptiPlex GX1 running R5A30. The changes I had done for the 150 did not seem to bother the 350. May have even helped?

I don't have any solutions for the 150 no sound at this time.
Mike

If you're in the US and can get channel listings from zap2it, don't scan it'll only roach the good data you already have or interfer with getting good data.

There are two common causes for this kind of problem (BTW - It's a common one and has been around almost as long as I've been playing with KnoppMyth.)

- Selecting the wrong frequency set. Trying the other 2-3 options is easy if you know how. Run mythtv-setup and look under "General" - http://www.knoppmythwiki.org/index.php?page=GettingBackIntoMytTVsetup

- Hauppage introduced another new tuner chip that the ivtv driver you have doesn't support yet. To determine if this is the case check the log files http://www.knoppmythwiki.org/index.php?page=CheckingLogFiles and if necessary update your driver http://www.knoppmythwiki.org/index.php?page=CompileIvtv

Mike (mjl) - You've got a new tuner chip that isn't supported in 0.4.4 (the M2523_5N_E) you'll need to go to a newer version. Skip 0.4.5 and go straight to the prerelease of 0.4.6. I've been running it for ~6 hours solid now and poking at it every way I can think of. So far it's been rock solid.

Follow the CompileIvtv direction with these changes (this should take all of 10 minutes, minus testing time).

In step 2 change the wget to:

In step 3 change the tar and cd to:


Edit - Fixed the DL and rename for step 2.

Hi tjc,

Don't get a swell head but you are good! I am going to try the upgrade of the driver on my R5C7 since that is where the card is installed currently.

Let me get busy and get back to you with the results.
Thank you.
Mike

Hi tjc,

Had a few issues,
http://ivtvdriver.org/viewcvs/ivtv/branches/0.4.tar.gz?view=tar
didn't like that part...
mv /root/0.4.tar.gz ivtv-0.4.6pre.tar.gz
didn't like that either

I get picture, poorly, audio mostly noise, some program material faintly

Will have to try some more tomorrow.
Have a great day and thanks for dogging it with me.

tjc:

Upgraded ivtv to 0.4.6 and everything's working smoothly now, audio included. Thanks for the help!

Mike I think something else must be borked. I know this si taking coals to Newcastle, but have you checked the feed you're using for this box to make sure it's good? Also have you run through the mythtv-setup dropped the card and added it back?

Hi tjc,

Since it seems to have worked for MTeeter, it should have worked for me. Maybe I did too many steps. I am going to re-install my 350 to make sure my R5C7 system is ok.

Mike
Edit 11:22, Remove nonfunction 150 & reinstalled 350, dumped the card, reselected the card, select inputs, rebooted and I have my tv back. So much for the borking theory..., goes on the back burner for a couple of days, can't afford to loose much more hair.
Thanks for the help anyway!
Mike

I too, purchased one of these PVR-150's from Circuit City with the rebate and through reading this forum I have everything setup nicely except for the sound. I followed the direction of this post, upgrading to ivtv 0.4.6pre, but still have no audio.

I figure the more people we have looking at this, the quicker we can solve this problem.

I'm running R5C7:

Sempron 3400+
NVidia GeForce 6100
Generic Speakers

I haven't been able to hear any audio in any part of KnoppMyth at all, but I know the speakers work because they work in XP Pro.

Hi disruptor108,

Hey, thanks for popping in

Your issue "sounds" different though. You should have sound for music. Rip a music cd and see if you can play it. As root you can run # alsamixer to make sure things aren't Mute. If it generates an error, try # alsaconf

My audio is only tv related, 99.9% noise with only a hint of program.

Mike

Mike have you tried diddling with the finetuning? I'm reminded of a case where someone was using us-cable when they where getting us-cable-irc. Also just to be complete, plow through the configuration and make sure the settings in your recording profiles and the rest are sane.

tjc, do you still advice to update ivtv to (pre) version 0.4.6?
Is it stable so far?

No crashes yet.
