Ethernet and avb protocol

Is The ethernetport avb compatible?

Hi @Koen11,

Welcome to HP Support Community!

We noticed that this thread hasn't had any updates in a while since your original post; while this is rare, we didn't want this post to remain unanswered, so here's the solution to your query. We hope it helps you and everyone viewing this post 😊

Based on the specifications available for the HP Notebook - 15-da0076nb, here's what I can confirm:

Ethernet Port Details

Your laptop includes an Integrated 10/100/1000 GbE LAN port, which means it supports:

• Gigabit Ethernet (1 Gbps)
• Backwards compatibility with 100 Mbps and 10 Mbps networks

Is It AVB-Compatible?

AVB (Audio Video Bridging) is a set of IEEE standards (like 802.1AS, 802.1Qav) designed for real-time, low-latency audio/video streaming over Ethernet. For a device to be AVB-compatible, the Ethernet controller must:

• Support hardware-level time synchronization
• Be certified for AVB standards

Unfortunately, most consumer-grade Ethernet adapters, including the one in the HP 15-da0076nb, do not support AVB out of the box. AVB is typically found in:

• Professional audio/video equipment
• Specialized network cards (e.g., Intel i210 series)

What You Can Do

If you need AVB support for professional audio/video work:

• You can use an external AVB-compatible USB or Thunderbolt Ethernet adapter.
• Or consider a dedicated AVB switch and endpoint hardware.

Hello,

Before I confirm anything, I need a bit more detail so I don’t assume the wrong requirement — AVB (Audio Video Bridging) support depends on the NIC chipset, driver, and firmware, not the laptop model itself.

I need you to confirm:

1. What is the exact Ethernet NIC shown in Device Manager?
   (Example: Realtek RTL8168/8111, Realtek PCIe GBE Family Controller, etc.)

2. Are you asking about:

   • IEEE 802.1BA AVB (Audio Video Bridging),

   • Dante,

   • AES67,

   • or another time-sensitive networking requirement?

3. What device or system are you trying to connect to that requires AVB?

Early guidance (I’ll confirm after your answers):

Most HP consumer notebooks, including the 15-da series, typically ship with Realtek GBE controllers which do NOT support AVB.
AVB generally requires:

• Intel I210 or I225-based NICs

• Special AVB-certified drivers

• OS-level TSN support (which Windows 11 consumer builds don’t provide)

But I want your NIC model first to confirm.
