Squeezebox Touch -- Modifications

[soundcheck]

Buffer setting issues are usually caused by EDO. People who installed EDO
won't be able to use the TT buffersettings. EDO comes with a couple of fixed buffersettings on its own.

Usually it requires a complete removal of EDO and a factory reset to get the toolbox installed properly.

Hi Klaus,

I recently acquired a DAC that says - any device that supports USB audio class 2.0 specifications could work with this DAC.

I am not getting any music out of it though, but my SBT could detect the DAC at the Digital output, and it says:

USB -Audio - 'XXXbrand' USB Audio 2.0[info] >

Status: Stop
Speed: High
Connection: Direct
Type: Asyn
Format: S32_LE
Rates: 44100........192000

Does it mean the DAC doesn't support SBT EDO?
Perhap there is a way to toggle the status to "Go"?

Thanks!

EDO (with tailored generic Alsa USB driver) needs to support the DAC.

If your DAC is Class Compliant Alsa should suppport it.

Type:

cat /proc/asound/cards

You'll find all recognized sounddevices listed.

Thanks again! Will take a look!

Hi there.

FYI.

Squeezelite a nice little (very slim) headless Squeezeboxclient respectively emulator.
It's a tiny application, based on squeezslave, that'll sit in the background and waits for orders via iPeng, browser or any other SB control panel.
The traffic will be routed to your soundinterface of choice at up to 32/384.

You can use Squeezelite pretty much on all platforms - OSX/WIN/Linux and many different processor architectures (even on your Open-Wrt router or Raspberry PI devices it'll work).


Basically there's no need to have a Squeezebox anymore. You can achieve
similar performance with a Raspberry PI and a Hifimediy Sabre USB DAC (25$+45$ -- 70$ in total)

Note: iPad and Droid tablets are covered already. You'll find similar streaming apps for a couple of bucks in the app stores.



Bottom line.

Now we can make every coffeemaker part of the Squeeze Streaming Universe at close to 0 cost.

Thx to Adrian Smith (also known as Triode (EDO) in the SB world) to bring the squeezslave project back to live. I'm sure he'll listen to constructive feedback over @ SB forums.


Great stuff. Enjoy. I do.

Cheers

PS:
I havn't managed to get SL-arm6 properly working on the Touch (Triode is looking into it). I tried Squeezeslave-ARM some time back and made it work. But at that time squeezeslave didn't sound as good as squeezeplay. That's why I left it alone.

If I manage to get squeezelite satisfactory working on the Touch, I'll release a new TT.

On my other Linux machines I got it working.

Hi there.

I need to correct above post a little.
##
Squeezelite is not BASED on Squeezeslave. It's written from scratch by Triode.
Sorry for the confusion.
The functionality though is almost identical.
##

Triode made the rev 1.0 RC2 available. It's working quite stable on my Touch and other computers.

Latest revision includes, beside several bugfixes, a priority setting feature to set the output thread
to a flexible priority (the thread runs SCHED_FIFO on preemtible kernels (realtime operation)). On earlier revisions SL output thread priority was fixed at SCHED_FIFO 40.

Performancewise it is IMO a head-2-head race with Squeezeplay at the moment. I do think Squeezelite got higher potential. But I still have difficulties to get the Linux environment properly tweaked for it. SL responds very sensitve to changes in the environment. As soon as I try to add (some of) my known optimizations it hangs up. Pretty weired. It behaves completely different than Squeezeplay.


Cheers

What do you think, can SB Touch with Squeezelite stream flawlessly 384K to an USB sound card like Amanero?
Please give it try if you happen to have it.
Thanks

The newest SL version allows for up to 384khz.
The Logitechmediaserver still needs to be patched to accomplish 384.
There are people playing with it.

I'm not able to test it.

Hi folks.

Just to mention it again:

If you run squeezelite with default (buffer) values and priorities, it is quite stable.


If I talk about sensitive, I'm refering to a highly tweaked rt environment,
where all tasks,irq's etc. need to be well alligned.


No reason, for the hackers over here not to give it a try.

Cheers

Hi Soundcheck,

What ever happened to your planned TT40-EDO (& TT50) as mentioned back in August??

I'm only asking because I cant get TE80xxx (AudioGD DI-DSP) working properly on my sbt,, either uisng coax output (crackles and pops) or USB (not reconginsed)..

Thanks..
