    New Monitor No Sound from HDMI


    Just got a new monitor today, Samsung S24D300HL which I have plugged into my Nvidia Geforce GTX 745 video card via HDMI.

    Picture is great no problems there. However I have no sound at all. I've updated my graphics driver via Nvidia Experience program version 361.43 I've right clicked and went to Nvidia control panel audio tab and my monitor was listed there as audio under HDMI still no sound. I've restarted the computer a couple times. Checked Windows update. Switch to a different HDMI cord and still no sound. I've right clicked the speaker in the taskbar and went to playback and what I have is. Nvidia HDMI Output (Port 0) and Nvidia HDMI Output (Port 1) both say not plugged in. I'm confused about the Port 0 and Port 1 because there is only one HDMI spot on the back of the card.

    Any help appreciated.
    Thank you

    Both HDMI outputs say not plugged in therefore I cannot set them as default.

    Does the monitor have any settings for input/output? I use a HDTV as a monitor, and have to set that up too, for HDMI in, and optical out(to home cinema).

    It sounds like a "handshake" problem. Is the cable a 1.4 version or higher. Also from Wikipedia:

    Personal computers[edit]

    PCs with a DVI interface are capable of video output to an HDMI-enabled monitor.[7] Some PCs include an HDMI interface and may also be capable of HDMI audio output, depending on specific hardware.[167] For example, Intel's motherboard chipsets since the 945G and NVIDIA’s GeForce 8200/8300 motherboard chipsets are capable of 8-channel LPCM output over HDMI.[167][168] Eight-channel LPCM audio output over HDMI with a video card was first seen with the ATI Radeon HD 4850, which was released in June 2008 and is implemented by other video cards in the ATI Radeon HD 4000 series.[168][169][170][171][172] Linux can drive 8-channel LPCM audio over HDMI if the video card has the necessary hardware and implements the Advanced Linux Sound Architecture (ALSA).[173] The ATI Radeon HD 4000 series implements ALSA.[173][174] Cyberlink announced in June 2008 that they would update their PowerDVD playback software to allow 192 kHz/24-bit Blu-ray Disc audio decoding in Q3-Q4 of 2008.[175] Corel's WinDVD 9 Plus currently can has 96 kHz/24-bit Blu-ray Disc audio decoding.[176]
    Even with an HDMI output, a computer may not be able to produce signals that implement HDCP, Microsoft's Protected Video Path, or Microsoft's Protected Audio Path.[168][177] Several early graphic cards were labelled as "HDCP-enabled" but did not have the hardware needed for HDCP;[178] this included some graphic cards based on the ATI X1600 chipset and certain models of the NVIDIA Geforce 7900 series.[178] The first computer monitors that could process HDCP were released in 2005; by February 2006 a dozen different models had been released.[179][180] The Protected Video Path was enabled in graphic cards that had HDCP capability, since it was required for output of Blu-ray Disc video. In comparison, the Protected Audio Path was required only if a lossless audio bitstream (such as Dolby TrueHD or DTS-HD MA) was output.[168] Uncompressed LPCM audio, however, does not require a Protected Audio Path, and software programs such as PowerDVD and WinDVD can decode Dolby TrueHD and DTS-HD MA and output it as LPCM.[168][175][176] A limitation is that if the computer does not implement a Protected Audio Path, the audio must be downsampled to 16-bit 48 kHz but can still output at up to 8 channels.[168] No graphic cards were released in 2008 that implemented the Protected Audio Path.[168]
    The Asus Xonar HDAV1.3 became the first HDMI sound card that implemented the Protected Audio Path and could both bitstream and decode lossless audio (Dolby TrueHD and DTS-HD MA), although bitstreaming is only available if using the ArcSoft TotalMedia Theatre software.[181][182] It has an HDMI 1.3 input/output, and Asus says that it can work with most video cards on the market.[181][182][183]
    Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity.

    In September 2009, AMD announced the ATI Radeon HD 5000 series video cards, which have HDMI 1.3 output (deep color, xvYCC wide gamut capability and high bit rate audio), 8-channel LPCM over HDMI, and an integrated HD audio controller with a Protected Audio Path that allows bitstream output over HDMI for AAC, Dolby AC-3, Dolby TrueHD and DTS Master Audio formats.[184][185][186] The ATI Radeon HD 5870 released in September 2009 is the first video card that allows bitstream output over HDMI for Dolby TrueHD and DTS-HD Master Audio.[186] The AMD Radeon HD 6000 Series implements HDMI 1.4a. The AMD Radeon HD 7000 Series implements HDMI 1.4b.[187]
    In December 2010, it was announced that several computer vendors and display makers including Intel, AMD, Dell, Lenovo, Samsung, and LG would stop using LVDS (actually, FPD-Link) from 2013 and legacy DVI and VGA connectors from 2015, replacing them with DisplayPort and HDMI.[188][189]
    On August 27, 2012, Asus announced a new 27 in (69 cm) monitor which can produce its native resolution of 25601440 via HDMI 1.4.[190][191]
    On September 18, 2014, Nvidia launched GeForce GTX 980 and GTX 970 (with GM204 chip) with HDMI 2.0 support. On January 22, 2015, GeForce GTX 960 (with GM206 chip) launched with HDMI 2.0 support. On March 17, 2015, GeForce GTX TITAN X(GM200) launched with HDMI 2.0 support. On June 1, 2015, GeForce GTX 980 Ti (with GM200 chip) launched with HDMI 2.0 support. On August 20, 2015, GeForce GTX 950 (with GM206 chip) launched with HDMI 2.0 support

    Did the cable come with the monitor? Or did you buy it extra? It might be printed on the cable, but if it came with the monitor, it's probably the correct version, also if the packing list in the manual says High Speed Cable, it should be OK and it's just a handshake problem: HDCP / HDMI Handshake Troubleshooting and Guidelines when HDMI Equipment produces snow or no signal

    It was purchased separately and just says high speed on it. No version number.

    I tried a different cable as well says high speed, but still no sound.

    It should be ok then, take a look at the trouble shooting link I posted.
