Does MiniDP converted to HDMI still include audio?

After MiniDP is converted to HDMI, it still comes with audio.

DisplayPort (DP) and HDMI are both digital audio-video interfaces. The DP interface can be used to simultaneously transmit audio and video signals, and both audio and video can be transmitted separately without interfering with each other. The DP audio path can have up to 8 channels of 24-bit 192 kHz uncompressed PCM audio, or it can encapsulate compressed audio formats in the audio stream.

Because the DP protocol is different from the HDMI protocol, usually a single chip is used for protocol conversion when converting from DP to HDMI, splitting the DP signal into audio and video synchronized HDMI signals. MiniDP is also a type of DP, just with a different interface shape, so MiniDP to HDMI conversion can also transmit audio signals.

However, it should be noted that although HDMI signals and DP signals are both audio and video transmitted synchronously, if the display does not support audio decoding, there will still be no sound. In this case, if you want to use audio, you can connect the audio output from the host. For example, if it is a computer host, you can use a 3.5mm audio cable or optical audio (if the motherboard supports SPDIF optical audio output).

In addition, if the sound device (such as a speaker) only supports analog audio input, then an HDMI to 3.5mm/ stereo output audio converter may be needed. If the HDMI display has built-in speakers or audio decoding, then you can directly use the audio function. If only audio decoding is available, there will generally be a 3.5mm audio output interface at the display interface (most HDMI displays support 3.5mm audio output). At this time, simply connect headphones or speakers to this interface to hear the sound.

In summary, after MiniDP is converted to HDMI, audio signals can be transmitted. However, the specific usage situation needs to be determined based on the support of the display and the sound device.
