HVR 5525 DVB-S tuner not working

jlaba · November 7, 2021 at 8:30 AM

Hi all,

I have a problem with my HVR 5525 card. The DVB-C and DVB-T tuner is found and is working, But the DVB-S Tuner is not showing up at all. In /dev/dvb only one adapter is created and in dmesg the Montage tuner could not be loaded. Here is the coressponding log:

I wonder why it tries the m88ds3103 instead of the m88rs6000t mentioned at linuxtv.org? And also the error m88ds3103 4-0069: Unknown device. Chip_id=00 is strange.

I have tested gentoo with kernel 5.10.76 and the current LibreElec live image. Both behave like the same.

Any hints are warmly welcomed!

Regards!

pls try also a image from test.libreelec.tv, they include a much more recent kernel (5.15 at this time)

likewise they ninja changed the the chips at the board at some time

Luckily its a Hauppauge Card so the support should be doable at some point.

If it still does not work with the 5.15 kernel try to report it to https://github.com/b-rad-NDi/Ubun…-kernel-builder, he is the driver dev that does the upstreaming to the kernel for Hauppauge/WinTV

Hi CvH,

thanks for your reply! I had now access to the system again and I tested the libreelec test image. It shows the same behaviour. I have opened an issue at github (s. https://github.com/b-rad-NDi/Ubun…lder/issues/134).

Regards!
