Tivo losing sound - comes back after reboot

[Darren King]

G'day, I have exactly the same problem as zollymonsta, been happening pretty much ever since I plugged the TiVo in after getting it, details as follows:
- only occurs on the ABC, never on any other channels
- intermittent fault, have not noticed any patterns
- I have observed it occur only when TiVo records, and seems equally likely to occur both
a. when TiVo has to change channels from another channel (sound always fine on other channels) to record on ABC, and/or
b. when TiVo already on ABC and not recording (and sound already OK) and then starts a recording
- can't remember it ever occurring when I change channel to ABC manually
- when the problem occurs and I happen to be watching, a manual change of channel away from ABC and then back to ABC fixes it (but only for that occurrence)

Background:
- TiVo bought from US, sent direct to Darren King for installation of a tuner & imaging and install of a large HDD (who did a great job, great support afterward, highly recommended!)
- Initial reception problems traced to crap antenna & crap house cabling, fixed with lush new antenna, quad-shielded cable and f-connectors all the way along signal path

If anyone can help, my wife, David Attenborough and I would be very appreciative!

Cheers,
Cods

Just as an update:

NOTE: This issue is only relevant for TiVo's with the "Mark 2" stereo sound modification (that is, the sound processor chip change)

It was discovered a month or so ago that there was indeed a way to make the TiVo perform better in this department.

What was discovered is that if the TiVo went to record something on the SAME channel it could lose sound because the palmod software did not re-check the sound standard. In some circumstances this does cause an issue. The original palmod software was designed to only check the sound standard on the change of a channel as in theory this should not need re-checking if the channel does not change.... well, it turns out that it DOES need to be checked again to cater for instances of signal fluctuations and other abnormalities which can happen with wireless signals.

Subsequently a fix has been tested by some people exeriencing this issue (I could never get it to happen to me!) and it works. The fix was implemented by Keith Wilkinson to the Australian version of palmod and the relevant new palmod package with some other cosmetic changes is available on the oztivo website.

Or I have just the palmod.o file which is compatible with the current one on the R1.5 20051128 oztivo image which I have attached to this message. Simply rename the current palmod.o file in the /lib/modules directory (linux command for renaming is: mv palmod.o palmod.bak) and copy on this one. DO NOT try and simply copy on the new palmod.o over the old one. Either rename the old one or delete it first. Copy on the new one and then reboot the TiVo.

This fix is not required for NZ people or anyone running a TiVo without the Mark 2 stereo chip with a PAL tuner.

The next OzTiVo image release will have this fix as standard.
