TV Tuner support?

Post by Speeddymon » 2020/05/14 00:55:34

Hi,

I realize RedHat removed a lot of driver support from v8 and so I was wondering what TV Tuners are still supported?

# lsusb |head -1
Bus 002 Device 003: ID 2040:b123 Hauppauge

I have this device and I setup both Plex and VLC on a fresh CentOS 8 install but I can't seem to get either of them to play from the device.
It works fine connected to my Xbox (It's the Xbox one TV tuner card, but according to the Plex site, it is supposed to work without issue on PC via Plex).

Any idea if this device will work with CentOS 8? If not, what devices are compatible with the default (not centos-plus) kernel?

Code: Select all

[root@centos8 ~]# grep -i 2040 /lib/modules/$(uname -r)/modules.* | grep -i b123
/lib/modules/4.18.0-147.8.1.el8_1.x86_64/modules.alias:alias usb:v2040pB123d*dc*dsc*dp*ic*isc*ip*in* cx231xx
So, the driver is there. Is the firmware? Did you read dmesg to see if there are any errors listed?

Thanks for the pointers, I was at a total loss.
Everything looks ok here, and I believe this confirms the firmware is available as well.

I got it working!
Turns out Plex doesn't allow local playback, you instead have to go to app.plex.tv and playback that way.
