Re: [slim] Community Funded Squeezebox Replacement - Would you be interested?

2013-01-26 Thread JohnSwenson

There should be no soldering needed to make the board useful. The wifi
is a mini-PCIe form factor, it just pushes into the socket. You DO have
to plug in an antenna of some sort, its a standard UFL jack on the
module. 

All the other connectors are on the board, putting it in the case is
just putting it in place so the connectors go through the holes and
either screwing the board in or pushing down onto some of those nylon
hold downs. 

I really want to put the DAC on the GEN1 board. It's a new design I
haven't used before and I want to have a platform to play around with
the internal DSP. I want to find out how good we can make this sound. 

Someone else brought up an interesting aspect, if the DSP is done in the
DAC, it can't be applied to the S/PDIF or USB. For just straight
playback, that won't matter since the only thing I will be doing with at
least at first is the interpolation filter, which is already included in
any external DAC. For long term GEN2 it might be best to have the FPGA
DSP based system, then you can do anything you want and it will be
useful for all outputs. But that is definitely NOT going to be in GEN1.


I did some more poking around the processor/memory issues, it's a bit
more complicated than I thought at first. It looks like the best bet for
GEN1 is a 720MHz processor and 256MB RAM. This does not have TDMI
interface, it does have an LCD interface. For GEN2 a 1GHz processor and
512MB RAM, this comes with a full blown video controller and built in
HDMI and VGA interface. No need for external chips, just hook up
connectors. The GEN1 is a much simpler board layout task so I would like
to go with it. I COULD do the faster processor from the get-go, put its
more work and costs a little more (about $10 more for the board, about
$15 more for the processor and $20 more for the  memory).

I actually did a full quote on board costs and its actually right around
what I thought, the board and assembly for a GEN1 will be $64 for 25,
The GEN2 is about $75. So the rest of the cost is the parts which look
like around $90 to $100 for a Gen 1. So that hits the $170 for the
board. It's $35 for the wifi module which you can add at any time. The
place I'm working with does the parts procurement as well, so it's just
send files and money and a couple weeks later get a box of fully
assembled boards. 

The Gen1 board will have no display, so all development has to be over
ssh or serial port. I'll probably put a serial port on it so you can
have a hardware console during boot. 

So it looks like it will have an ethernet jack, 2 USB-A jacks, serial
jack, S/PDIF coax, 2 RCA jacks. The big question is, should it have a
headphone jack. The easy, inexpensive headphone circuits are not all
that great and add more complexity to the board. I know how to make a
REALLY good headphone amp, but it will add quite a bit of complexity to
the board and some extra cost. So what are your thoughts:
1; no headphone jack
2; simple, cheap, not so great
3; whole hog really good, but complex and pricy.

That sounds really great : the specs you propose (i.e. included DAC and
defaut jacks) and the related price make sense to me .
I personnaly don't need the TOSLINK and depending on complexity, an IR
receiver could be great (as I found it grear that with SB3 you don't
need to power your phone or computer to do play / pause / modify
volume)

As far as the headphone is concerned, a cheap jack could be useful for
debugging the interface during night development but is not mandatory

(btw, count me in)

Re: [slim] Community Funded Squeezebox Replacement - Would you be interested?

2013-01-26 Thread JJZolx

I'd vote simple, cheap headphone jack.

Did you forget to mention the SD card slot, or would there be no
external slot?

Would most connectors be on just the rear edge of the board? Not
important on the first go 'round, but I think it's important, rather
than having a player with connectors and cables coming off of several
sides. The headphone jack could be on the side, and also the SD card
slot, if there is one.

Is it possible to design a box that could completely power down the wifi
radio when it's not in use?

What bitrates would this Squeezebox ultimately be capable of?

Ok, then it makes sense.
I'm definitely willing to pay for it just to make it possible for you to
experiment with it so we can get something really great in GEN2.

I would go with the slower CPU and less memory for GEN1, since GEN1 is
just a temporary experimentation platform to get to GEN2 it doesn't make
sense that people should have to pay for the more expensive CPU/memory
both in GEN1 and GEN2. For GEN2 I definitely want the faster CPU/memory
to make it more future proof.

For GEN2, some kind of line-in would be nice if you believe GEN2 in the
future could be packaged in a case with built-in speakers, the line-in
on the Squeezebox Boom can be really useful if you want to use it as a
speaker for external sources like a smart phone or similar device. If
you think a product with built-in speakers would require a completely
different board, a line-in doesn't make sense at this stage.

IR and HDMI would also be of interest for GEN2, but that has already
been mentioned earlier.

For GEN1 it isn't needed at all.
For GEN2 something with similar audio quality as the Squeezeboxes is
probably a good idea.

In my opinion the S/PDIF is enough.
However, if you can add the TOSLINK without adding a lot of complexity
or cost, having both TOSLINK and S/PDIF in GEN2 could be nice for people
who only have free TOSLINK connections in their DACs/Amplifiers.

I think keeping all the flash on a card (micros SD) is probably best as
it makes it easy to avoid the "bricking" scenario - asking someone to
remove the card and reflash it from a PC is much easier than the
debricking process we have with touch or the non existant debrick on
radio...  For a community project there will be much less QA so there is
a risk of this...

These are indeed the reasons that this product will stand out. 
Audiophile performance on a DIY budget.  Even if the rest of the world
remains unconvinced about Squeezebox and prefers their Sonos or Airplay
systems, in this community we know the value of the Squeezebox
ecosystem, and whilst off-the-shelf hardware is already filling some of
the player gap, I think a player whose design focus from the outset is
very high SQ will go like hot cakes in this community.  I'd also hope
that the power supply part will conform to John's very high standards in
this area.

I'm no software developer, I've already got all the Squeezeboxes I need
(and a spare Touch in the loft) but I still want in on one of the first
batch of 'our' player.  I might use it to replace the currently dormant
SB2 that I built into my DIY preamp a couple of years ago.  Any chance
of a balanced output as well as RCA?

Sounding great to me John.  Few questions:

1) Do we need Wifi could a usb dongle be used at lower cost?
2) Assume we keep all flash on the SD/microSD to avoid the bricking case
(see above case)
3) Are both usb ports on an internal hub or are they separate
controllers on the processor
4) can you point me at the datasheet for the processor you are planning
on?

1.  Irrespective of whether you rip or download at some point you need
to (a) get the track registered with the database and (b) amend the
meta-data (a lot of my music is classical so, believe, me, I know all
about the inadequacies of CDDB-acquired meta-data!).  So at present you
do that on a "PC/Mac/whatever" and then, as a separate process, run a
scanner to perform the data-acquisition in bulk, periodically rescanning
and, as people with large collections complain about, waiting for that
to happen.  If you decide your metadata isn't right, edit it, rescan &
wait.  Why? 

Wouldn't it be better to have the rip/download functionality aware of
the server D/B update it with each rip or download as it works?  And
wouldn't it be at least as effective to amend the D/B's version of the
acquired metadata via the server's web interface and, if you wanted,
then amend the embedded metadata in the track from that?

2.  Why?

3. You only need players once you've got something to stream, unless
you're relying entirely on streaming from the internet.

FWIW I have a headless server built into one of the old Hiper cases
which, sadly, are no longer made & getting rarer on eBay.  This box was
built to the dimensions & finish of a typical domestic audio or video
appliance.  I've fitted a fanless  mini-ITX board & lap-top optical &
hard drives.   Sitting inside the cabinet with the rest of my kit it's
inaudible.  It's also headless.  It can rip CDs automatically and
management is done by web interfaces; the keyboard and screen are needed
but they're just not directly attached to the server after initial
setup.  The latter isn't perfect because it isn't integrated with the
LMS database.  

If the acquisition. metadata editing and file shuffling facilities were
integrated with the server there'd be no need to have the latter scan
anything unless I wanted a precaution against my logging in via SSH &
moving things round behind the server's back but this could be handled
by some sort of stock-taking scan could be backgrounded.

You can't, it doesn't. There's no real extra playlist management beyond

Going through some old boxes and came across this beauty. Many a happy

one to the higher resolution display back in the day. 

As you can see - it has 'gone sticky', like many of the others did. What
is the cure for this? Or does anyone have a spare case for an SB1? It
still works and has that lovely vintage sound (ah-hem...!) - would be
great to get it back into circulation in the guest bedroom.

I like the concept of the wifi module connecting via ethernet. The
processor chip has two ethernet ports on an internal switch, the idea is
that one goes to the outside world and the other goes to the wifi. As
far as the processor and software is concerned the wifi is just another
device on the network. You literally don't have to care whether
something is coming from wired or wifi. The software just has to worry
about a single ethernet connection. Any wifi setup issues are dealt with
by browsing to the wifi web page, either through the wifi or wired port,
so the firmware on the processor doesn't have to know anything about it.
I just think it makes things so much simpler from a software
perspective. Since I am thinking about configuration of the player be
controlled by an internal web server, this can just link to the wifi
module's web page. Since it is connected through a hardware switch, you
can always get to the wifi configuration via a hardwired connection to
the player. 

Each USB port has it's own separate controller, each of which can either
be a device or host. 

The processor is a TI AM3358, the technical reference manual gives a lot
of detail on the USB subsystem:

Its worth us looking into the usb subsystem seeing as it seems to be
differnet from the ones I know work - its not ehci based from what I can
see.  I don't want us to have a Pi disaster on the usb ports...  What we
need to look for is positive use cases of linux iso code working with
the musb usb controller.

When I was asking around after I couldn't get the Pi working properly
with UAC2, the BeagleBone was a device I was told to stay away from.

It's nice to be able to go back to the drawing board before you even

Following up my own post. Bad form, I know. I was also told by the same
person that I wouldn't have a problem with either the BeagleBoard XM or
the Pandaboard. Neither of which I have tried myself. Both of these use
a USB3320 PHY for the host hub.

The XM looks to have a AM3715 which has a dedicated usb host port using
ehci - which would be preferable.  (though I'm not saying we shoudl use
this, just that I think a host only port using ehci is possibly
preferable)

[slim] Does crossfade work?

2013-01-26 Thread tomasito

Hello, 
I have a squeezebox touch and a squeezebix duet.
I tried enabling the crossfade effect in both systems, but they don't
work/crossfade?
I even went into the mysquezebox website to eanble the crossfade, it
still didn't work.
Any suggestions will be appreciated.
Thanks in advance

[slim] Internet Radio Streaming Down?

2013-01-26 Thread ismarketing

Reported the problem to Logitech earlier today.  Can stream any radio
stations - not favorites, nothing.

Tried on the classic, a touch and a SB Radio.

Anyone else having this problem?

Thanks

2013-01-26 Thread Recoveryone

There may be a more technical term for it, but I have notice the same on
my touch compared to my Transporter and SB3.  I assume it has to do with
the added GUI that brings up the album art, making the crossfade slower
or not at all.

Re: [slim] Does crossfade work?

2013-01-26 Thread aubuti

Works fine for me when using my local LMS. Over the new year I had a
Touch, SB2, and Duet Receiver synchronized and crossfading just fine. Of
course, crossfade also works un-sync'd.

How many seconds have you specified for the crossfade, and what type of
crossfade? Note that if you choose "Smart Crossfade" then LMS will not
crossfade consecutive tracks from the same album.

I've spent all afternoon looking at this, what I can come up with is
that the USB ports on the Am3358 are EHCI compatible when used in host
mode. (hardware pins forcing host mode). There is a driver that works
for this (OMAP_ehci). The problem seems to be with the musb driver which
is the one specifically written to handle the OTG modes, which is what
the kernels use since they detect what it actually is. This may be wrong
since I haven't actually found anybody outright saying this, but from
reading between the lines this is what seems to be happening. If this is
true it might be possible to force the use of the ehci driver rather
than the musb driver. 

There have also been reports that these issues only occur with newer
kernels and that things were working with older kernels. 

The AM3715 was one of my top contenders, but it does not support DDR2 or
DDR3 memory, only LPDDR, which has a memory speed about half of what you
can get from DDR2. The memory chips are also quite a bit more expensive
and larger than regular DDR2 memory chips. 

I've ordered a BeagleBone, it should be here this coming week sometime
and I can actually play with it and actually see what happens with
different kernels and DACs.
