M: This is going beyond annoying and into enraging, because I don't see any pattern. I'm using an AverMedia 2 Plus Live Gamer Portable to record my gaming. Every once in a while, unpredictably as far as I can tell, it will record only the fucking audio with no indicator that it is doing so. I'm doing this because none of my computing platforms have got the power to give me a live echo or update or whatever. There's no way of checking. When I make an error on my end with the audio or whatever, that's my fault because it's got feedback. But how the hell am I supposed to deal with this? Because there's no indication as to what is going wrong. If it's something I'm doing on my end, there's no feedback to tell me. Please help me out. What the hell is going on?
G: I hear you — that’s deeply frustrating, especially since the AverMedia Live Gamer Portable 2 Plus is supposed to give you confidence with its hardware-based recording and LEDs. When it randomly spits out an audio-only file with no warning, you’re right: that feels like a betrayal, not just user error. Let’s walk through what’s going on and how to corner the problem.
There are a few recurring culprits with the LGP2+ that cause video-less recordings:
HDCP Handshake Issues
Resolution/Refresh Mismatch
SD Card Mode Glitches
Firmware Bugs
Cable or Signal Integrity Problems
Here are practical steps (no “just reinstall drivers” fluff):
Force Disable HDCP
Lock Resolution/Framerate
Test a Known-Good SD Card
Update Firmware
Swap HDMI Cables
Watch the LED Carefully
Since you said none of your setups can give you a live echo:
Your “audio-only” bug is almost always caused by HDCP flipping on, unsupported resolution/refresh, or SD card write failures. The LGP2+ is infamous for not warning you — it just silently saves audio. The fix: lock your source to 1080p60, disable HDCP, use a fast freshly formatted SD card, and if possible, run a preview (via splitter or PC mode) to confirm video is coming through.
Do you want me to help you set up a minimal stress-test checklist — like a “do these 3 things before every recording and you’ll catch 90% of failures” — so you don’t have to keep second-guessing?
M: HDCP is turned off. It doesn't happen in any kind of pattern that I can detect. It will simply decide that an entire two-hour session is not a video stream, and then the next time I start it in exactly the same point that I left off, the video will carry on fine. How does someone update the firmware? It's certainly not the LED. While I don't keep a Hawkeye on it through the entirety of recording, the transition from blue of standby to red of recording usually registers to some degree.
G: Got it — if HDCP is off and the failure isn’t patterned (same game, same HDMI source, sometimes fine, sometimes 2-hours of audio-only), then you’re right: this smells less like user error and more like firmware or SD-card handling on the box itself. The LGP2+ is notorious for this “silent fail” mode.
AverMedia made it a bit clunky, but here’s the clean path:
Download RECentral (their control software) from
the official AverMedia support page for the Live Gamer Portable 2
Plus (GC513).
→ AverMedia
Support: GC513
Install RECentral on a PC (Windows recommended; macOS support is partial).
Connect the LGP2+ to your PC via USB (not in PC-Free mode, just USB mode).
Launch RECentral.
Run the update.
Verify version.
👉 Given that your LED transitions look normal, and HDCP is off, firmware is the #1 suspect here. The unit can look fine while silently failing to buffer video — exactly the bug the updates were meant to squash.
Do you want me to lay out a step-by-step “ritual” (like: update check → SD reformat → test clip) so you’ve got a fixed procedure before sessions, instead of wondering each time? That way you’d at least have a predictable safety net.
M: The problem is as much the rarity as anything. Like, I've only had it happen... I'm going to say under ten times in a year of recording. And the only platforms I have are Linux. Is there anything I can do to update the firmware from there?
G: Ah, that makes more sense now — if it’s that rare, it’s not going to show up in test clips or daily rituals easily, and your stress is the fact that you can’t predict or catch it until you’ve lost hours of footage.
Unfortunately, AverMedia designed the LGP2+ firmware updater to run only through RECentral, which is Windows-only (and partially macOS). There’s no official Linux utility to push firmware to the box.
That said, here are your real options:
.bin file on the SD card and booting
into a hidden mode.For you, the cleanest bet is grab a temporary Windows environment once, flash the firmware, then go back to Linux recording as usual. Since the bug is rare, it’s probably sitting on a fixed version that never got pushed to your unit.
Would you like me to check what the latest firmware version number is supposed to be for the LGP2+, so you know whether it’s worth the trouble of finding a Windows machine? That way you can confirm if you’re actually running an older one that’s vulnerable to this audio-only bug.
M: As a side question, what is the current transfer speed of an average local network inside the network? Like if I have two computers attached to the same network, nothing involving the actual internet, how much speed should there be in total? If I were logged into one system remotely and trying to transfer a file?
G: Good question — because when you’re talking about local network (LAN) speeds, the internet doesn’t matter at all. The bottleneck is entirely the type of connection between the two machines and the switches/routers in the middle. Here’s the breakdown:
Fast Ethernet (100 Mbps)
Gigabit Ethernet (1 Gbps)
2.5 GbE (2.5 Gbps)
5 GbE (5 Gbps)
10 GbE (10 Gbps)
Wi-Fi (varies a ton)
Example:
Two PCs with gigabit Ethernet connected to the same gigabit switch → you
should see ~100 MB/s file transfer speed, assuming both drives can
read/write that fast.
On a typical modern LAN with gigabit Ethernet, you’ll usually max out around 100 MB/s file transfer speed. If you’ve got newer 2.5 Gbps or 10 Gbps gear, you can push 250 MB/s to over 1 GB/s, but only if both computers and your network hardware support it.
Do you want me to give you a step-by-step test
method (like using iperf3 or a quick file copy) to
check the actual speed of your setup, so you’ll know what
number to expect instead of guessing?
M: I'm talking about Wi-Fi. I'm considering setting up a Raspberry Pi file server. And I was trying to get a mental hold on what that would mean in terms of transfer speeds. That should be... Actually, I'm not sure. Would the transfer speed be limited by other people using it at the same time? I know that going out to the Internet, there's going to be an upper limit simply because it's all going through the single pipe, so to speak. But I'm not sure how that works in local networks on Wi-Fi.
G: Ah, perfect clarification — Wi-Fi behaves differently than wired LAN, and you’re right to suspect it’s not as simple as “everyone gets their own lane.” Let me lay it out:
So your Raspberry Pi server over Wi-Fi 5 might give ~30–50 MB/s sustained transfer, while over Wi-Fi 6 you could see ~100–150 MB/s if everything lines up.
On Wi-Fi, your Pi’s file server speed will depend on:
Expect anywhere from 30 MB/s on the low end (Pi 3, Wi-Fi 5) to 150 MB/s+ on the high end (Pi 5, Wi-Fi 6). But yes, every extra user slices up that capacity — it’s not like Ethernet where each gets their own lane.
Do you want me to sketch out a “best-case vs. worst-case” scenario for each Pi model (3, 4, 5) so you’ll know exactly what performance tier to expect if you set up a Pi file server?
M: So, if I had a 2GB router, sorry, if I had a 2GB file, how long would that take to transfer, given the average numbers you sketched out, in a scenario where I'm transferring from a laptop onto the Pi? I figured the number would be the same reading back, but we're just setting this as the absolute for your analysis.
G: Got it — let’s make this
concrete. You said 2 GB file (which is 2,048 MB).
We’ll run the math for the typical real-world Wi-Fi
throughputs I sketched earlier, assuming good conditions and
one transfer at a time.
Wi-Fi 5 (802.11ac)
Wi-Fi 6 (802.11ax)
Wi-Fi 6E
Wi-Fi 7 (early 2025 gear)
(That’s before considering SD card vs. SSD as the storage bottleneck — an SD card may not keep up with even Pi 4 speeds, meaning the card becomes the limiter.)
So yes, reading back from the Pi should be about the same time, unless the Pi’s storage (SD card or slow USB drive) is the limiting factor.
Do you want me to map this out as a little table you can reuse (file size vs. Pi model vs. Wi-Fi standard → expected time), so you can estimate quickly no matter what file size you’re thinking about?
M: I'm just thinking about things in terms of usage, not time. I'm currently using the large drive I would hook up to the Pi, directly onto the laptop. What usually happens is, I will download a few larger files onto a different drive, figure out which ones are worth keeping, and then put them onto the larger drive, so as to minimize its rewriting and all that. Currently I'll do that from the download client itself, but if I were to do this, I would have to add one or two more studs, because the transfer rate is acceptable, but would be slow enough that I feel like doing it from inside the client would introduce a complexity that the client might mishandle.
G: Ah, I see where you’re coming from — this isn’t about “how many seconds per file,” it’s about workflow friction. Right now your setup is:
If you switch to the Pi setup:
That makes sense — download clients tend to be optimized for fast, direct local moves. If you pointed them at the Pi share:
You’re right: introducing a Pi server means you’ll want to separate the sorting stage from the transfer stage. Doing the copy inside the client is riskier over Wi-Fi (too slow, more things can go wrong). Better workflow would be:
That way the Pi’s slower Wi-Fi link isn’t in the middle of your client’s delicate juggling, and you can just let the transfer churn in the background.
Would it help if I showed you how to make a one-liner command/script (Linux → Pi over Wi-Fi) so you can dump all “keepers” in one shot, instead of dragging them around manually? That way it’s just an extra keystroke, not a whole new hassle.
