USB DAC for Samsung S95C

[Jazigo]

I did rerun my tests on the newest update (2202 Tizen 9): There is still 95ms of latency on the optical out port. The same for HDMI Arc.

This is 95 ms more time that extracting audio from the Lindy 2x2 HDMI 8K60 Matrix before it reaches the TV.

Was the TV set as "PC" in Input source? I believe that turns off all video processing and reduces latency.

I am not sure, actually. I just connected my laptop and made sure game-mode was turned on (disabled a lot of stuff that gets greyed out in the menus).

I would have expected USB DAC support on recent Samsung TVs to be more popular among the ASR crowd!

How are people typically connecting DACs to Samsung TVs, via Toslink or HDMI ARC? Both options seem less practical to me.

Has anyone run into similar issues using the Apple USB-C to 3.5mm dongle with a Samsung TV or any other source? Sound seems normal when watching TV broadcasts, but some songs on Spotify sound like vinyl records.

I have older Samsung plasmas myself but use them only as displays, don't even use ARC due its limitations let alone needing tv-based source of audio or even video. Never even occurred to me to use a dac on a tv....sort of what sucked me into the thread However, if I add a tv to my active speakers from what I'd seen you needed primarily hdmi or wireless....not used to having usb be for many applications on a tv, tho.

Some bus-powered USB DACs work with certain Android and Tizen TVs, providing analog audio output on TVs that lack a dedicated analog jack. It's very practical as there are no lip sync issues + no volume control issues. Feature is poorly documented on Samsung TVs, basically one line in manual.

In the end, I bought the Steinberg IXO22 and it works reasonably well. Initially I tried to connect the interface to the USB port on the left side of the One Connect box for better cable management, but for some reason this resulted in stuttering audio. Upon connecting it to one of the two USB ports in the middle, it started working normally. Lip sync is off immediately after power‑on but quickly synchronizes. I haven't noticed any clicks or pops, so the problem was likely related to the Apple USB‑C to 3.5 mm adapter.

Unrelated rant: the One Connect box, at least on this model, is not well engineered. The cable connecting the box to the screen is awful, it’s extremely stiff and the connectors on both ends have a poor locking mechanism, so even a gentle movement of the screen can cause a weak connection and a myriad of issues. As a bonus, the Samsung full motion wall mount for this TV, does not leave space for the One Connect box cable, so the TV can't be pressed fully against the wall because the cable interferes.

I found a workaround for stuttering audio after powering on when using the Steinberg IXO22. Switch the audio output to optical or the TV's internal speakers, then switch back to the Steinberg IXO22 (or any USB DAC you are using).
