Many many thanks for all you guys do.

After the first attempted tune the device/resource becomes unavailable so I have to run this to kill it.


rice@amd:~$ sudo fuser /dev/video0
[sudo] password for rice:

Trying to tune after the kill results in this in the logs after streaming to the tuner failed timeout after 32s

Linux Ubuntu 22.04 desktop, AMD 9600x cpu, channels version 2025.03.02.2319.

I’m getting clean hiccup free video at 60fps now but I’m not getting any audio. There is no mention on any audio errors concerning audio in the logs. Here are the following m3u formats I’ve tried.


#EXTM3U
#EXTINF:-1, channel-id="usb-hdmi",USB HDMI Capture
capture://v4l2/video0

#EXTM3U
#EXTINF:-1, channel-id="usb-hdmi",USB HDMI Capture
capture://v4l2/video0?audio=hw:Video,0

#EXTM3U
#EXTINF:-1, channel-id="usb-hdmi",USB HDMI Capture
capture://v4l2/video0?framerate=60&audio=plughw:Video,0

#EXTM3U

#EXTM3U
#EXTINF:-1, channel-id="usb-hdmi",USB HDMI Capture

#EXTM3U

capture://v4l2/video0?framerate=60&audio=plughw:Video,0

#EXTM3U

capture://v4l2/video0?framerate=60&audio=alsa_input.usb-UltraSemi_USB2_Video_20210621-02.analog-stereo

If I run this command I get both video and audio capture, playback from the output.mkv file in VLC is successful with both audio and video.


ffmpeg -f v4l2 -framerate 60 -i /dev/video0 -f alsa -i hw:Video,0 -c:v copy -c:a aac output.mkv

Output of audio sources in terminal


rice@amd:~$ pactl list sources | grep -E 'Name:|Description:'

Same log errors

Still same on Mac (assumingly due to capture device perms)

Fresh diagnostics on 61d5aa07-d474-4bc8-9300-7db8f867452d .

I am still unable to get the sound to come through my Linux setup but I see others are having the same issue. I tried the latest config in the post and got the exact same error messages so that is promising.

I have made progress and created a home assistant automation that is based on a sensor that detects the channel number in Channels DVR and will then run a script to change the channel via a RF blaster.
