I've been having terrible issues trying to playback some h.265 (1080p 3284kbps 23fps) media off my home server via SMB.

The video freezes and lags after about 2 seconds of playback while the audio continues to play. The controls become unresponsive and sometimes the screen goes black with the audio still playing and the only fix is to turn the TV off and turn it back on again.

The audio codec is TrueHD 5.1/2.0 1476kbps 32bit 48,000khz if that's relevant, but the audio seems to playback just fine.

There are several BDPGS subtitle tracks.

h.265 is on the supported codec list for my TV.

The manual (page 65) also seems to indicate support.

It seems like TrueHD is NOT supported in apps and only works over HDMI on this TV due to licensing issues.

But the sound seems to play perfectly regardless. I also have other media with TrueHD tracks that have no issues playing back. Heck I also have tons media with tracks encoded in DTSHD-MA, Dolby TrueHD and Dolby Atmos which should definitely NOT be supported in hardware and those files also work just fine

I have other h.265 media in 4K 35,000kbps 24fps with TrueHD Audio with BDPGS subs which playback perfectly.

I also have lots of 4K files encoded in AV1 (2541kbps) with Opus Audio which are also not supported in hardware which work just fine.

The files playback just fine over my network in VLC for Windows over 1gbps Ethernet via SMB.

The files also playback perfectly on my phone in VLC for Android over 5G Wi-Fi via SMB.

I've tried:

Disabling hardware acceleration (much worse)
Forcing full acceleration (slight improvement, but still un-watchable)
Enabling frame skipping (no improvement)
Increasing network caching to 30,000ms (slight improvement)
Switching from wired ethernet (100mbps on this TV) to 5G Wi-Fi (speed test gets 201mbps) (no improvement)
Forcing OpenGL ES 2 (much worse)
Forcing OpenGL ES 2 for audio (worse)
Forcing Digital Audio Output (no improvement)
Disabling SMB1.0 (no difference, I'm pretty sure my server only does 3.0)
Disabling Block Filtering (slight improvement, still un-watchable)
Disabling Automatic Subtitle Loading (read there was a bug with this) (no improvement)
Updating VLC (Google Play says it's the latest version)
Updating the TV OS (already up-to-date)
Restarting the TV via settings menu (to clear RAM) (no difference)
Clearing the Cache (no difference)

So is this an unfixable issue with the hardware decoder in the TV? Despite the fact that other similar files work?

I would hate to have to re-encode this, I've got close to 1TB of media encoded this way. 😂

Thanks in advance.

My 3.5mm Audio Jack on my motherboard recently died and I found a Modi 2 Uber on ebay for $90 CAD (with tax and shipping) and snapped it up.

The power switch on the back moves left and right instead of up and down and is really loose and doesn't stay in any position.

Despite this, the device is detected in Windows 10. The default USB 2.0 Audio drivers installed themselves automatically.

The front LED light does nothing when I press the button on the front and I can't get any sound out.

I'm just using some really cheap earbuds connected with an RCA to 3.5mm adaptor. I figured I can turn the gain way down in windows.

However, even with the gain set to the max in windows, there is still no sound.

I didn't blow up my ear buds, they still work fine with my phone.

I'm using a brand-new shielded USB cable.

The power brick it came with does not appear to be the one supplied by Schiit, but it is the correct voltage (Output 16VAC 500mA 8W, Input 120VAC 60HZ) . Nothing changes regardless of whether I have it plugged into AC power or not.

Is this even worth fixing, or should I just get a refund?

If it is worth fixing, how do I go about it?

Thanks.

Cannot playback some 1080p h.265 Videos via SMB on Sony Bravia 4K VH21

Did I just buy a Dead Modi 2 Uber?
