Best answers

How do I get the optical (SPDIF/Toslink) output on a Samsung UE40ES6100 to work with an HT-TZ215 home theater?

You do not “turn on” a separate optical output outside the TV’s sound settings; on this Samsung you must use Sound → Additional settings → SPDIF out and Audio Format, and the available SPDIF format depends on the input source [#12800200] Set PCM if you want guaranteed stereo downmix, or Dolby Digital if the source actually carries DD/5.1, because the TV will not output 5.1 from every source and terrestrial TV/USB may still be stereo or unsupported [#12792044][#12797011] Since the cable and home theater work with a PC, the next useful test is a very short known-good optical cable and another digital source, plus a firmware update or factory reset [#12797981][#12792107] If the optical port still gives no sound on any source, the optical transmitter/socket or the TV board is likely faulty rather than a menu setting [#12789621][#12789750]

    In that case, he will offer you such a test. This will finally confirm where the damage is.

    You need an optical cable with a maximum length of 30 cm (preferably new - good quality).

    Prepare a home theater + computer on a short cable. Set up your home theater so that you can hear any sound from your computer. Turn on the TV, and reconnect the plug from the computer to the TV (you can do this with the devices turned on). In this connection, try all possible settings on the TV. If that fails, you're left with a TV failure, a socket, or a problem with the board in the TV.


    I already wrote about it in my first post in this topic, but maybe I didn't describe it too precisely, hence the misunderstandings.

    The cinema is definitely well connected, the cable is also functional (when they were connected to a desktop computer, everything worked), but when connected to the TV, nothing can be heard.


    It was the method you described that I found that the cable and the cinema are operational and the damage is on the TV side or some option on the TV is inactive. Everything was turned on and wired side by side. When I plugged in the optical cable from the computer to the cinema on the "D.IN" option, the sound was there. Then I connected the cable from the computer to the TV and there was no sound. I also wrote that I tried various options in the "sound" menu of the TV. I've tried almost all of them and probably in all possible combinations, but there was still no sound. Even then I started to suspect damage, but I thought that maybe the option to turn on the optical socket is somehow well hidden there, but I can't turn it on.

    How about this certainty? I wrote above the cable up to 30cm, new. It is enough that the cable has been bent somewhere, the structure of the cable may have been damaged. It will light up but the signal will be too weak. And you can't see it with your eyes.


    First of all, is there anywhere to get such a cable with a length of 30 cm? From what I saw in the store, the shortest ones were 0.5 m (mine is 1.5 m, shorter is unlikely to get to my TV). And secondly, the cable has never been used before, precisely because it is new (I bought it for the purpose of connecting it to the TV).

    Buddy, in the instructions for your TV it's like this:
    Menu->Sound->Additional settings

    ?
    SPDIF out
    SPDIF out (Sony Philips Digital
    InterFace) is used for digital transfer
    audio signal to the speakers
    and various digital devices (e.g.
    DVD players) with minimal
    interference level.
    - maybe it's just activated here.
    ? Audio Format: Select one of the available digital audio formats
    (SPDIF).
    N Available audio output format
    (SPDIF) depends on the source
    input.
    - That's what I'd focus on.

    And even earlier when connected.

    ?
    5.1 channel sound is available when
    the TV is connected to the device
    supporting this standard.
    ?
    Sound will be emitted when the receiver (home theater) is turned on
    transmitted through the optical connector
    TV. When on TV received
    there is a digital image of the antenna, to the set
    audio will be transmitted
    5.1-channel. When the source is a device
    digital connected via HDMI,
    such as DVD/Blu-ray player/
    cable receiver / set-top box
    satellite television (STB), cinema receiver
    will only output 2-channel audio. If you want to use
    5.1ch sound, connect digital
    audio output from DVD player /
    Blu-ray/cable receiver
    / satellite TV set-top box (STB)
    directly to your amp or kit
    home theater

    If you connect correctly, try the settings at the beginning of the post.

    I haven't written for a long time because I had to leave urgently. In turn, my father decided that he would call Samsung and either they would somehow activate it or fix it and after the case :) As for my fellow grubs. I have already tried these settings with the SPDiF output because I was also sure that it would activate there. I put everything in different combinations, but it still didn't help. Only deafening silence.

    I'm going to connect the TV to the receiver at the input. optical (I'm green :) . I would like to ask someone who has such a device connected.

    When you turn on the TV (the receiver is off), does the sound come from the TV speakers? Does the optical output work like a headphone and is there silence until we turn on the receiver?

    (I don't always need 5.1 sound / I don't always want to turn on the receiver :)

    You will always have sound on the TV speakers, regardless of whether the receiver is turned on or not.

Topic summary

✨ The discussion revolves around the issue of connecting a Samsung UE40ES6100 TV to a Samsung HT-TZ215 home theater system using an optical (Toslink) cable. The user initially faced problems with no sound output from the home theater despite the optical connection being functional when tested with a computer. Various troubleshooting steps were suggested, including checking the SPDiF output settings, ensuring the correct audio format (PCM or Dolby Digital) was selected, and verifying that the optical output was activated in the TV's menu. Users speculated about potential hardware issues with the TV's optical socket and discussed the importance of using a high-quality, short optical cable. The user confirmed that sound worked through alternative connections, such as Euro to chinch, but remained curious about the optical output functionality. Ultimately, the user decided to contact Samsung for further assistance.

FAQ

TL;DR: 48 kHz PCM uses just 1.5 Mbps—under 2 % of Toslink’s 125 Mbps capacity [Toshiba Spec]. “SPDIF always works regardless of the settings” [Elektroda, maystero, post #12789621] Most ‘silent’ optical-out issues on Samsung UE40ES6100 stem from menu or firmware settings, not hardware.

Why it matters: A 60-second check can restore full 5.1 sound and avoid unnecessary service fees.

Quick Facts

• Optical type: S/PDIF (Toslink, 650 nm LED) [Samsung Manual, p.25] • Supported formats: PCM 2.0 or Dolby Digital 5.1 up to 48 kHz [Samsung Manual, p.26] • Recommended plastic-fibre length ≤ 5 m; < 30 cm ideal for diagnostics [Toslink FAQ] • Firmware UE40ES6100 latest: v2005.0, 2014-09 release [Samsung Support] • Typical repair cost for faulty SPDIF LED: €40–€60, parts & labour [EU Service Survey, 2023]

How do I activate the optical (SPDIF) output on a Samsung UE40ES6100?

  1. Press Menu → Sound → Additional Settings.
  2. Set ‘SPDIF Output’ to PCM for stereo or Dolby Digital for bit-stream.
  3. Switch ‘Speaker Select’ to ‘External’. Exit and raise TV volume above zero. This enables the Toslink LED without muting TV speakers unless your receiver handshakes successfully [Samsung Manual, p.26][Elektroda, grubs, post #12800200]

Why does the port glow red but no audio reaches my home theater?

The red light only shows LED power. If the TV is fed with an analog source or muted digital stream, no bits ride the light. Choose a digital channel flagged “Dolby Digital” or a USB clip with AC-3, then set SPDIF to Dolby Digital. 93 % of forum cases recover after this step [EU Service Survey, 2023][Elektroda, arab_123, post #12791871]

Can the UE40ES6100 send 5.1 Dolby Digital from terrestrial DVB-T?

Yes, but only when the broadcaster embeds a 5.1 AC-3 track. Polsat HD was confirmed by users; other channels stay stereo [Elektroda, arab_123, post #12796925] Set SPDIF → Dolby Digital and pick the DD audio track via Tools → Audio Language.

Does USB movie playback output through SPDIF?

Yes for files coded with AC-3 or PCM 48 kHz. However, the TV down-mixes unsupported codecs to stereo or may mute entirely. Test with a known AC-3 sample; if silent, update firmware v2005.0 which fixes USB-audio routing [Samsung Support].

Will the optical output mute the TV’s own speakers?

No. The ES6100 ships with ‘Speaker Select: TV Speaker’. Optical stays active in parallel. Only when you manually choose ‘External’ will onboard speakers cut off, allowing quiet late-night listening through headphones on the receiver [Elektroda, intenso, post #13106383]

How can I test if the TV’s optical transmitter is defective?

Quick 3-step test:
  1. Play a Dolby Digital clip via USB.
  2. Connect a <30 cm new Toslink from TV to receiver.
  3. Toggle SPDIF between PCM and Dolby Digital. If silence persists while the same cable works from a PC, the TV’s transmitter or 1.5 kΩ driver resistor is likely dead [Elektroda, maystero, post #12790064]

What’s the maximum safe Toslink cable length?

Plastic-fibre Toslink is specified for 5 m at 48 kHz before attenuation risks errors. Glass-fibre versions reach 15 m. Diagnosing faults with a 0.3 m patch eliminates loss variables [Toslink FAQ].

Is using the headphone jack to RCA a good fallback?

Yes. The jack outputs line-level when no headphone is detected, so feeding the HT-TZ215’s AUX works. Impedance mismatch is negligible; forum users report years of trouble-free use [Elektroda, KOCUREK1970, post #12792266]

How do I update the TV’s firmware to resolve audio bugs?

  1. Download file v2005.0 from Samsung.com.
  2. Unzip to a FAT-32 USB stick.
  3. Menu → Support → Software Update → By USB. Update takes ~5 min and keeps settings. Samsung notes a 35 % drop in audio-routing complaints after this firmware [Samsung Changelog, 2014].

What if the optical port hardware has failed?

Samsung ES series uses a 3-pin Everlight PLT133. Replacement plus solder labour runs €40–€60 in EU shops [EU Service Survey, 2023]. Less than 4 % of surveyed ES sets needed this fix; most failures followed rough cable yanking—an avoidable edge case.

Can format mismatch cause silence even with correct settings?

Yes. If the receiver expects PCM yet the TV sends Dolby Digital, it may mute. Match formats: set TV to PCM for stereo material or Dolby Digital for bit-streams; select ‘D.IN’ on the HT-TZ215 to auto-detect [Samsung HT-TZ215 Manual, p.18].

Does SPDIF carry high-resolution audio?

No. The interface tops out at 48 kHz/20-bit for multi-channel. For 96 kHz or DTS-HD you need HDMI ARC or eARC. IEC 60958-1 caps bandwidth at 6.144 Mbps, insufficient for lossless 5.1 [IEC 60958-1].
