A few months back, I installed a new distribution amp, and at the same
time rebuilt all of the cables in RG6-quad with compression fittings,
etc. One test I could try is swapping the inputs on the two cards, to
see if any symptoms move. I tend to agree about the dying card. All
has been happy for many months after the input rebuild, and I haven't
touched anything significant lately. MythTV was upgraded to 0.22 in
March, and kernel and cx-18 drivers are both dated Feb 20.
Incidentally, on the last reboot audio came back on the card, and has
stayed back. I still haven't re-enabled it in MythTV, but keep checking
it every few days to make sure it hasn't gone bad, again. I have a
conflict on June 18, and if it's still working the, I'll re-enable it.
By then I may also have stuff around the house under control, and it'll
be time to take this machine down. Got a new CPU a while back - about
20% speed boost, for $5.00 at a flea market, adding another Gig of DRAM
from a different machine I'm decommissioning - and I'll remove,
dust-out, and reseat both capture cards.
I get more fearful about semiconductors and their longevity every
generation. I'm working in 32nM these days - hard to believe,
considering I started by testing 4-mask metal gate over 30 years ago.
Thanks,
