🎵 Raspberry Pi Octo 8-Channel Sound Card Review

Check out my amazing solution! (I'm proud of it. :) ) I've been able to confirm that simultaneous recording and playback on multiple channels works well. I had a Pi 4B with two channels out and four channels in, all 16-bit/192kHz. The datasheet for the chip claims it also supports 24-bit I/O and I see no reason to doubt that. Also, I haven't tried doing all the 8-out and 6-in at the same time yet, but I assume it works. The sound quality is fine both outside and inside. There was some headache.

I really hate leaving negative reviews. I bought it to see if it would work for a couple of audio/ALSA/Linux projects I'm working on. I received a small 3x3 inch box with the components neatly packaged inside. No user documentation. I went to the site and did not find any user documentation either (if there is any, write about it in the comments). I then decided that the most valuable place to visit is the user forum. I'm midweek and have yet to get approval for my post from the forum admin…

I use several Octos for scientific data acquisition and they perform very well up to 48 fps (some distortion at 96 fps). The inputs are very clean, low-noise and virtually free of interfering signals. In use they are very reliable, no unexplained failures or breakdowns. The device connects directly to the Pi's I2S bus, making it much more reliable than a USB audio interface. Installation is pretty easy, just edit a little text in /boot/config.txt to enable the required overlay. Octo is an…

I purchased this item, connected it to my latest PI and updated the PI firmware and software as instructed. After initial tests, when everything seemed fine, I tried to record a concert with it. Well, bad news. The PI crashed after a few minutes of the recording session. I rebooted, and then again, a few minutes later, another crash. I tried again in a different location with a more powerful power supply (just in case the PI runs out of power). the same again. And with a simple stereo…

Extremely poor quality - this is an alpha product that needs an overhaul. There are major issues with current isolation, hiss, pops, and instability. On the hardware side, it has inferior components and soldering. I've been looking for an article like this for a whole house audio solution but it just doesn't work, even for the main stereo output.

Very, very powerful machine. I almost never review anything, but I was horrified that this amazing piece of technology got bad reviews. Nothing compares to the capabilities of this device for the money. This thing turns your Raspberry Pi into a very powerful audio workhorse that can be used with software like Modep and Tracktion Waveform. Effects and mixing 6 inputs simultaneously on a $35 computer in real time still feels like science fiction to me. If you hate setting up Linux machines and…
