In my Rasperry Pi3 I have used the same MicroSD card for 8 years, it runs 24/7.
Transcend 600x 8GB MLC card, it cost £3.89 at the time
I don't mean to imply that I have 8 years uptime, I have re-imaged the card a few times during major version updates etc. But same card for 8 years with no failure/corruption.
That's good, but if you're not copying content or caching to the card you've barely got a couple of gigs written to it over that time I'd think.
So, after some thought, I think im just going to stick to a fast MicroSD. Running an external SSD means my nice tidy FLIRC case set up won't look so tidy.
I also enabled unlimited caching to disk last night for a test and it worked fantastically. The write life of modern SD cards is actually quite high so I don't think this is unsafe as it used to be. I currently have a 64GB Sandisk Extreme Pro V30 card installed, but have ordered a 256GB model instead. I think at £25 for a 256GB card, even if it died every year (which it won't), then who cares?
So this thread has got my attention since I use a remotely hosted Jellyfin Server at a datacenter I look after, and have a Starlink connection at home.
If I ran my Pi5 LE install on an SSD instead of a MicroSD, this means I could set the cache/buffer type to store the entire file on disk as quickly as my internet connection could download it, which would be better for me than the 1GB max size currently configurable in RAM.
So how do I go about installing the LE image to an SSD and booting from it, rather than MicroSD?
Howdy all, an important change that I certainly overlooked is that the settings for readahead/cache which we previously implemented via the advancedsettings.xml file within the userdata folder have now been replaced by a GUI option under Settings > Services > Cache.
I wondered why I was having playback buffering issues since updating to LE12 on my Starlink connection until I noticed the system was not reading ahead.
These new GUI options override whatever you have in the advancedsettings.xml file.
This is documented on the Kodi site and I am sure its in the release notes somewhere!
Hopefully this saves some of you some pain!
The workaround is to use AUX1/AUX2 and then you can put the UI at 60hz. I haven't had any issues with this configuration and you can rename the inputs so although it's odd to be forced to use those ports, it has been smooth sailing as long as you plug into one of those.
I am fairly sure I tried this, as have others and it made no difference. Perhaps it’s unique to the 3800H. I have a 3600H and pretty sure using AUX made no difference but I am going to try again.

Can confirm this makes NO difference on my AVR-X 3600H. Using AUX2 still resulted in no signal from a cold start of all equipment until reboot of Pi whilst keeping the AVR on.
I’ve noticed that when I initially reported this problem, switch sources could eventually get display at 60Hz… However in the most recent 2 builds or so including 12, switching sources does not recover the display.
Only a reboot of the Pi does. And once everything has been off for a bit, it will not give me a display.
The pi devs are currently looking into an issue related to loss of HDMI sync. It's not specifically about 4K60, but you never know, it might be related
This is interesting. But how do we go about reporting this thread as a bug for investigation as we have no idea currently if it’s on anyone’s radar for investigation?
Bumping to keep this current. Has anyone made any progress on identifying the cause of this issue?
Ive still made no further development on this. Cannot get 4k60 to work consistently. Does not happen with any other source.

Are you able to test directly to TV without the Denon? I can do so when I get home later.
With resolution set to 3840x2160 @ 30FPS, I have not had this issue occur once in the last 2 weeks. The UI is more sluggish but its not slow. I always use 'adjust display refresh rate' on start/stop as well.
There's a problem with 60FPS output, how do we work out if its a Denon problem or a Pi problem though.... Could run directly into the TV for a while I suppose but this may be a false test as I won't be passing through DTS/Dolby HD etc.
Display MoreI bet our Denon-Receivers are the problem.
I didnt hear so far from other Receiver-Brands with simlilar Problems.But who knows.
In my case an apple-tv-4k +Infuse does display-like a perfect job in 3840x2160@60hz+dv.
So because of this, its actually also possible the the Pi does something wrong...
(But with an apple-tv-4k you can actually forget audio-passthrough. Its not possible.
You only have the option converted everything PCM, stay at DD 5.1 or even Stereo.
Dolby Atmos works only with content that has E-AC3 with joint Object Coding so far.)Staying at 3840x2160@30hz is a valid solution for the problem.
Changing constantly refresh-rate&resolution if i stay at 1920x1080x30hz is not a solution for me
As there is a better resizing algorithm for the pi5 on the road the better upscaling capability might not be an argument anymore to stay at 1080p and let the receiver/tv rescale.
I bet its the raspberry Pi to be honest.... Denon receivers are a long standing top selling AV product. I bet theres far less people forcing 60Hz output on raspberry Pi's than there are Denon users with standard AV equipment.
The problem is clearly 60Hz output.
What could be the reason?
It’s faultless with 4k and 30hz set. I have adjust display refresh to start stop.
Does the GUI resolution limit not achieve this even when the output is set to 4K?
I have just tested this at 30FPS and confirm the issue no longer occurs so this is specific to 60FPS output.
None of the previous settings have worked for me. Infact they have made it worse.
What video mode should I be setting my Denon to. Enhanced etc….?
I might try 30fps for the UI and see if that works like you say.
Switching to AUX2 on my Denon AVR-X3600H has not solved this problem.
I have just added hdmi_force_hotplug=1 to config.txt and will see what that does.
I had the exact same problem as described in the first post. My setup is Pi 5 8GB connected to Denon AVR X2800HDAB connected to Sony Bravia XR55A80L. If the Pi source was selected/active on Denon while booting up Pi everything worked fine. As soon as I changed the source on Denon and then tried to get back to Pi I would not get video (No signal) in 50+% cases. Audio, on the other hand, worked (I could hear UI sounds).
That was the case as long as I had Pi connected to CBL/SAT or Media Player HDMI input on Denon. Moving Pi to AUX1 or AUX2 HDMI input (two of three 8K ports on Denon), for some reason, solved the issue. Switching to Pi source now works flawlessly.
I'm running Pi at 3840x2160, 60Hz with this added to the cmdline.txt:
Codevideo=HDMI-A-1:3840x2160M@60D,margin_left=0,margin_right=0,margin_top=0,margin_bottom=0In addition to that, I added the following to the config.txt:
Codehdmi_force_hotplug=1 disable_overscan=1
I will try this, namely changing to one of the other inputs, I am using CBL/SAT.
If that doesn’t do it I’ll add those hdmi hot plug and overscan lines to my config.
If changing the input alone does this, I wonder what’s special about those on Denon AVRs.
I can confirm that this no-signal issue still occurs with a Pi5. I am running 60fps.
Are there any other options we can enable in the config.txt.
Do I need to dump and fix the EDID?
Ive just got my Pi5 to replace my 4 and am setting it up as we speak. I am using a direct micro HDMI to HDMI cable (HDMI 2.0).
I am running 60FPS, I will report back.
