Geogg – my experience with the loss of sound before the update was similar to yours, the only way to fix it was to fully power down the Humax, if it was recording at the time it would not actually fully power down, so the sound could not be retrieved until there was nothing recording.

I eventually solved the issue by buying an AV amp and running through that (I bought the amp to get better sound than from the TV, not just to fix this issue), the problem has still happened a couple of times in the last 9 months, but that is no where near the amount of times as when it was plugged directly to the Sharp TV.

I like the Humax unit for the most part, however I would not recommend it to others because of this sound issue which I feel is an HDMI issue that Humax are not interested in fixing.

My advice to you would be to take it back and get a full refund, a bit pessimistic but if enough people did it maybe they would fix the issue.

I didn’t have the loss of sound problem on the old software, only since loading the new.

Is there any way to go back to the old?

I had the sound problem as soon as I disabled ‘low power standby’ to enable aerial passthough in standby – but not had it since I enabled low power standby again – give that a go.

Of course you need to go back to dedicated aerial feed again.

Hello. I joined the forum last night because I had problems with an OTA update from Waltham transmitter. It stopped part way through, then zapped the recordings on my HDD which I had to then reformat. I downloaded the update and put it onto a USB stick with intensions of updating today. I switched the Humax on this morning and with seconds it started flashing alternate red and blue, it was doing an OTA update which it completed successfully. I’m not connected to the LAN, and didn’t insert the USB stick, so it can only have been an OTA update!

i have a humax-2000t/500gb/gb which i updated the firmware to the latest on the web site. after the update when i watch tv change the tv source to use computer there is no sound when i turn it back. i have tried new cables new ports etc and i still get no sound if i unplug the power and plug it back in the sound works again. if i change to other source and back again no sound again if i use a scart all works ok all the time.the picture is perfect via hdmi just no sound

seems to work for a minute but change it a couple of times it does it again

I tried turning the ‘low power standby’ off and on. I’ve found that, after turning the TV off and on, I always lose sound. But then with ‘low power standby’ ON, I can recover the sound by putting the humax to standby and back, while with ‘low power standby’ OFF, the humax will only recover sound if it’s unplugged and back on.

Both effects are reproducible.

Either way any recording would still be messed up. It seems to show a definite connection between the loop through mod and the sound problem.

Humax customer support have suggested an exchange – are they thinking the hardware has variations? I am inclined to return to retail, as an exchange might complicate my refund rights.
