| Post subject: | pvr-150 and R5D1 question |
I have two pvr-150's and I noticed in the upgrade notes post that there might be a problem with a few of the 150 tuner cards. Is there a way to see if I have one of the problem tuners with out having to open up my myth box? Thanks for all the help. And a big thank you to the Myth Team!!!! Matt |

Dial the capture volume back to 90% or less. The closer you push it to 100% the more distored it will get. |

... I turned it down, and it still buzzes.. but get this, when I plug the sound into line in of the box, the sound is beautiful - but is about 3 seconds earlier than the picture - I'm sure that is bacause of the buffer - It's annoying - and it has always been tinny - but moreso now... any other suggestions? Thanks

There's a setting you can poke in with ivtvctl that helps with some PVR-150/500 cards. Searching for recent posts that mention ivtvctl should turn up the info. |

What firmware version is your PVR-150 using? Code: dmesg | grep cx25840*
If you find the file size is 14000-ish bytes, then you need to upgrade to the newer, 16000-ish byte firmware. See ivtvdriver.org for instructions. |

Not that I have an answer, but I had the same issue with one of my 2 150s with R5C7. I'm troubleshooting a different issue now with R5D1 so I haven't played with it too much, but I did notice that the one that buzzed had a different tuner from the one that didn't. I'll try to check tonight to see which was the one that was buzzing. What was interesting was that after a reboot it would work fine for awhile, but then recordings later that night suddenly had the buzzing again. Gonz |

Here's what I got from "dmesg | grep tvee". tveeprom 2-0050: Hauppauge model 26552, rev F0A3, serial# 8966520 tveeprom 2-0050: tuner model is TCL MFNM05-4 (idx 103, type 43) tveeprom 2-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 2-0050: audio processor is CX25843 (idx 37) tveeprom 2-0050: decoder processor is CX25843 (idx 30) tveeprom 2-0050: has radio, has no IR remote tveeprom 3-0050: Hauppauge model 26552, rev G168, serial# 8880988 tveeprom 3-0050: tuner model is LG TAPE H001F MK3 (idx 68, type 47) tveeprom 3-0050: TV standards NTSC(M) (eeprom 0x08) tveeprom 3-0050: audio processor is CX25843 (idx 37) tveeprom 3-0050: decoder processor is CX25843 (idx 30) tveeprom 3-0050: has radio, has no IR remote I'm guessing that the first one is going to be my /dev/video0 so that's the culpret. Interesting thing is since I switched video cards and had to move it to another slot, I haven't had the issue. Strange. Gonz |

For the benefit of others... There was a patch posted in this thread that has fixed my tinny audio issue with a PVR-150. Don't know how to patch? Try this: Code: # man patch

I actually had to bump mine from 90% to 100% because my recordings were too quiet. I haven't noticed any problems. |
