bobfa Posted September 28, 2023 Author Share Posted September 28, 2023 It looks like they have optimized the hardware for manufacturing and upped the overall performance rather nicely. And some neat new features: A Power Switch! My Audio Systems Link to comment
bobfa Posted September 29, 2023 Author Share Posted September 29, 2023 I am thinking that this might be my selected hardware for Home Assistant. My Audio Systems Link to comment
firedog Posted September 29, 2023 Share Posted September 29, 2023 Looks like a nice upgrade. Is it actually available for order anywhere yet? Of course, I won't get one at least untill there are some nice "audiophile" cases available. The Computer Audiophile 1 Main listening (small home office): Main setup: Surge protector +>Isol-8 Mini sub Axis Power Strip/Isolation>QuietPC Low Noise Server>Roon (Audiolense DRC)>Stack Audio Link II>Kii Control>Kii Three (on their own electric circuit) >GIK Room Treatments. Secondary Path: Server with Audiolense RC>RPi4 or analog>Cayin iDAC6 MKII (tube mode) (XLR)>Kii Three BXT Bedroom: SBTouch to Cambridge Soundworks Desktop Setup. Living Room/Kitchen: Ropieee (RPi3b+ with touchscreen) + Schiit Modi3E to a pair of Morel Hogtalare. All absolute statements about audio are false Link to comment

Superdad Posted September 29, 2023 Share Posted September 29, 2023 It will be interesting to see if they begin offering a Compute Module 5 for embedded applications (such as in streamers). UpTone Audio LLC Link to comment
Archimago Posted September 29, 2023 Share Posted September 29, 2023 Faster Pi and all. Good for hobby projects I guess. Curious what you guys would use this for as audiophiles? My sense is that for a simple 2-channel endpoint the previous versions are more than adequate. These days, I've moved on to low-power MiniPCs (like this) and multichannel HDMI rather than Pi for my audio use given the software available like DSP, potential for HQPlayer, etc... Archimago's Musings: A "more objective" take for the Rational Audiophile. Beyond mere fidelity, into immersion and realism. R.I.P.

bambadoo Posted September 29, 2023 Share Posted September 29, 2023 You could check out CamillaDSP used on a rpi. Have 2 running. Great product. I think at least 8 channel dsp have been reported working great with rpi4 but the kernel used has to be quite fresh. Link to comment

There is talk of using it as an HQPlayer embedded machine. I'm interested in it for 12 channel Ravenna / AES67 audio. Founder of Audiophile Style | My Audio Systems Link to comment

Merging supports just x64 architecture. RAVENNA driver is mostly user space binary only component for x64 driver. With kernel space shim. So at the moment, it is not possible to support that on ARM platforms, even if one would want to. HQPlayer, first Embedded for a long time and now also Desktop has been supported on RPi4 (HQPlayer OS on Holo Red, etc). And I'm planning to support RPi5 with HQPlayer OS as well. But RAVENNA is limited by the driver implementation and tricky hardware requirements. USB/I2S/NAA of course works fine. blueninjasix and The Computer Audiophile 1 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

On bitbucket they write: "While the Butler OEM build may be build for multiple architecture (ARM, ARM64, x86, x86_64), the public Butler is built for the x86_64 architecture only" On the other hand there exists this project which implements a "daemon communicates with the driver [Merging Technologies ALSA RAVENNA/AES67 Driver] for control, configuration and status monitoring". They also test is on a Armbian NanoPi NEO2. Also audio-linux is using the Merging driver to implement a virtual ALSA audio device on a Raspberry Pi 4 and 5. I am curious about using AES67 on a Raspberry Pi 5, especially since it brings a Gigabit Ethernet with support of Precision Time Protocol (PTP). I wonder if that is beneficial for lower latencies?

Miska Posted February 26 Share Posted February 26 I don't know, I haven't used RAVENNA in a while. I gave up on the Linux driver, which didn't seem to like realtime kernel and few other things. Their newer driver worked fine on Windows and macOS. I don't have any RAVENNA hardware anymore. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
The Computer Audiophile Posted March 22 Share Posted March 22 I'm doing some really cool stuff on my new Pi 5, and preparing an article for next week. Question: Has anyone got a realtime kernel working on the 5? dericchan1 1 Founder of Audiophile Style | My Audio Systems Link to comment

But I don't know if rt linux is supported in that layer. Anyway, I am looking forward to your article. The Computer Audiophile 1 Link to comment

I'm using both the Debian with Desktop, and Ubuntu without desktop on my Pi. I don't think rt kernel is necessary, but I ran into one issue and wanted to try it. I see people have rt working on Pi 4, but I haven't found anything for Pi 5. Founder of Audiophile Style | My Audio Systems Link to comment

I see people have rt working on Pi 4, but I haven't found anything for Pi 5. Most ARM kernels are not safe with RT. This is because the of the flaky/bad programming practices in various drivers. So you may experience lockups and other strange behaviour with RT kernels on ARM. Plus the extra overhead involved with RT kernels may make the overall performance rather mediocre (drivers become threaded kernel processes, and lack of HyperThreading kind of functionality costs). This is the trade-off / balancing you need to consider between bandwidth/throughput driven (server) kernel where latency is bad, or latency driven (desktop) kernel where bandwidth/thoughtput is bad. yamamoto2002, DuckToller, blueninjasix and 1 other 1 1 2 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

yamamoto2002 Posted March 27 Share Posted March 27 USB and General purpose IO pins (GPIO) on Raspberry Pi 4 is connected directly to SoC, while those of Raspberry Pi 5 is connected to RP1 IO controller (South bridge) connected to SoC.
