I guess if you delete the log after a successful (with sound) boot. Otherwise you would be picking up errors from previous reboots

Mike / Steve,

Can't check logs at the mo (had to deactivate my port forwarding for my PS3 - another long story).....

But, soft/warm restarts make no difference with the Hitachi drive. Looks like I'll be taking them back.

Checking the date/time on the log entry would solve that,

... are you going to write it or shall I ?

Be my guest - my tcl/bash scripting skills are very rudimentary

But if somebody would write a C# shell for the TiVo I'd be cooking on gas...

Edit: I guess that'd mean porting Vista or XP to the PPC and getting it to run on a 54mhz processor with 16mb of memory... could be a challenge...

Here's the promised "reboot if no sound" script:

It checks the kernel logfile for the line "Unknown MSP Product" on the last bootup,
and reboots if it sees it.

It won't reboot if your tivo has been rebooted more than 5 times in the current hour,
just in case it would never restart with sound.

./nosound.tcl

Would running this script possibly result in the \var partition being reinitialised due to repeated reboots?

mikerr · 05-27-2008, 05:11 PM

It shouldn't cause that, no. But you still should have a backup of /var anyway

Tivo wipes the /var partition if it fails to bootup completely twice in succession,
- i.e if its filesystem check doesn't complete twice.

rc.sysinit.author runs after that point in the boot process.

Hi all,

The "no sound" problem has reappeared on my Tivo (it first happened just after I installed my Turbonet card approx. 1 year ago) but after at least 30 hard and soft reboots, it shows no sign of the sound coming back.

I therefore have what I hope is a simple question - if I purchased another Tivo, would I be able to rip out the old original drive, and replace it with my 120 Gb drive, together with my Turbonet card.

Is it that simple, or will I have to reconfigure anything. I am hoping not, because I have (had) it working just as I wanted, with a Digiguide connection so I can just right click on the program etc.

Cheers,

Gonzo

@mikerr

We've had overhead power line problems resulting in a several power outages that my UPS couldn't outlast. I've now got the no sound problem pretty consistently.
At some point I'll be brave and pull the TV stack apart to fiddle with the PSU but for now I assume I just binary FTP nosound.tcl into scripts and add

Code:

/var/hack/scripts/nosound.tcl &

to rc.sysinit.author ?

Cheers

Hi,

Its Dave from tivoland here.

I know I don't frequent the forum much these days, so much so that many users don't even know we exist anymore heheh :-)

Anyway, I have a hardware repair that we can carry out that can cure the "no sound but recoverable with warm boot" problem about 80% of the time.

I have never really heavily publicised it because its only around 80% effective. e.g. in some cases it doesn't work, but it doesn't make the problem any worse.

I would encourage users to go down the new PSU or tweak the PSU route first and if someone really wants it done as a last resort, it is an option.

Regs
Dave.

I keep losing sound after I hadinstalled a cache card, but I am not sure if mine is the same problem. It will be OK, but then sound will disappear (not just after a reboot). Sometimes changing channels will make it reappear, sometimes a soft reboot, sometimes a hard reboot (or 3). Can't put my hands on my multimeters at the moment...

AMc · 11-25-2009, 08:27 AM

@anyoneinracks as you have network access then I heartily recommend installing the script in post #35 above. I've had it going for ages, I'm sure eventually I'll have to replace the PSU but as you can just install it without 'going under the hood' it's a worthwhile stop gap.
IIRC there were sound problems with some early cachecards and certain RAM - if you don't get anywhere with the script then try removing the RAM as a test. Threads are probably in the archives by now.

anyoneinracks · 11-25-2009, 09:16 AM

Thanks - I'll give that a try, although I am not that keen on telling it to reboot of its own accord.
It is a new cache card, with supposedly 2.2 firmware

I thought i had got onto a foreign forum, did not understand a word of it, better stick to the virgin forum where they are not so clever

anyoneinracks · 11-25-2009, 10:37 AM

Its funny my posts always make perfect sense to me, even when they don't to anyone else.
Another funny about MY loss of sound is that it does it without the Tivo having been rebooted. I get the impresion that the "classic" loss of sound is a boot up problem.
