Hello again, Ken.
I'm aware of many of the pitfalls you mention, they have caused me one or
two headaches, and I agree with your conclusion. For now it's the only
small device at my disposal to experiment, develop and test and jam without
a laptop/screen.
Regarding the BeagleBone, IIRC, I think Jeremy didn't like quite that much
(I think I red that here in the list or maybe in his blog).
Maybe I think I was delaying going back to an early stage where I had to
investigate and compare platforms/devices (and prices) and to build up
again all that I've achieved at the moment.
Thanks for being so honest, maybe it's a little push for me to change the
platform finally.

After doing several Raspberry Pi projects, I'm
very negative on them, and
will never use them or recommend them again.
The built-in audio is crap, it's not even 16-bit.
The power management and regulation is non-existent and sucks. Raspberry
Pi's have destroyed a half-dozen SD cards of mine. The people in the Pi
community just shrug about this. It's unacceptable to me.
USB is a joke on Raspberry's. I wouldn't even try to use a USB device. The
Raspberry developers solved this problem by doubling the number of USB
ports on the new B+ units... without fixing any of the problems... so now
you can have twice the fail.
Ethernet is a joke; it's a USB device. To get the Pi to work reliably,
I've had to turn off USB2 mode anyway, so the Ethernet is beat-the-dog slow
too.
There's no databook for the chip, last I checked. Oh sure, there's a PDF
documenting a few of the features of the I/O ports. There's no actual
databook, like any good CPU core or SOC would have.
There's no real bootloader. Some call it a feature, I don't. There's no
built-in flash either (another thing touted as a feature that I consider a
design limitation).
I don't consider it economical since once you add up all the things you'll
need to get it to do work, you could buy a better-engineered platform for
the same price. And the Pi is slower than many of the other platforms in
its price range.
I'd instead recommend the BeagleBone Black for projects if you want a
mature, well-documented platform, or any number of the new exciting
ARM-based platforms coming out if you wanted to venture into something new.
I've done a few projects using the Pi over the past few years, both
pro-bono and professionally, and I would not recommend the platform to
anyone.
Sorry, I like to stay positive but my experience with Raspberry's has not
been good.
Keep looking and you'll probably quickly find something that works.

Hello dear all.
I'm testing a small interface for some musical and technological projects
which has an instrument input jack on one side and no audio output, just
USB on the other side. This IF works great but you have no physical audio
output to monitor/hear sound, so I thought I could enable internal audio
IF
(as I've done on other devices) and that will
be the audio output instead
of needing another second IF to get audio from.
So I decided to rescue some past investigations I made when first
researching about RPi, along with the great content generated by some
dear
great folks in here, and some new research one
after each problem.
First started from a Raspbian 2012 version which I had already tweaked
for
a headless autojamming/instrument effects/looper,
but got many issues
making step by step progresses that I briefly point here FWIW:
- Enabled internal IF on Raspbian 2012 [1]
- Found mmap problem regarding using Jackd with internal IF [2], even
tried
a module somebody compiled
- Tried switching to the new platform version, Raspbian 2015 (raspberrypi
3.2.27+) but there wasn't even /proc/asound
- Couldn't get to load snd-bcm2835 kernel module for internal soundcard
[4]
- Finally I got an error from the very raspi-config regarding internal
audio IF [5]
Although I continue researching, I guess somebody here has already gone
through some of this, but I'm wondering if it's already an abandoned
thing
by the makers themselves this thing of the
internal IF thing.
Thanks as always.
Greetings all.
