Does MiniDP to HDMI have audio?

  DisplayPort and HDMI are both digital audio and video interfaces; DisplayPort (DP interface) can be used to transmit audio and video signals simultaneously, and both audio and video can be transmitted separately without each other. The DP audio path can have up to 8 channels of 24-bit 192 kHz uncompressed PCM audio, and can also encapsulate compressed audio formats in the audio stream. Because the DP protocol is different from the HDMI protocol, a chip is generally used for protocol conversion when DP is converted to HDMI, splitting the DP signal into an HDMI signal with synchronized audio and video.
  Although both HDMI signals and DP signals transmit audio and video synchronously, if our monitor does not support audio decoding, there will still be no sound. At this time, if you want to use audio, you can connect the audio output from the host. If it is a computer host, you can use 3.5mm audio or optical audio (if the motherboard supports SPDIF optical audio output); if you do not want to connect audio from the host, and your sound device, such as speakers, only supports analog audio input, then you need an HDMI to 3.5mm/left and right channel output audio converter; if your HDMI monitor has built-in speakers or audio decoding, you can use it directly. If it only has audio decoding, there will generally be a 3.5mm audio output interface at the monitor interface (general HDMI monitors support 3.5mm audio output); at this time, connect your headphones or speakers to hear the sound.
