Mine works plug-and-play, use the envy24control GUI to manage it. 
Excellent sound quality!

I don't know - don't use VLC.

Could session management tools be set up to react to the appearance of 
Audacity's ports (I think they're always named the same) and reconnect them?

[LAU] Laptops for firewire based pro-audio on linux

Looking for A laptop that will perform well under linux.

Requirements...

* Must have graphics fast enough to run Unigine (my day job). Prefer nVidia (higher quality drivers, easier to move systems between my workstations and laptop)...

* Must be able to do low latency audio via firewire (I have a Presonus firebox, a Presonus fp8 and a TI based firewire express card)

* Preferably has eSata

My discoveries thus far...

There are specialist audio dealers that have custom built laptops for 2k to 2.5k even some in Australia.

Apple Mac Book pro seems to be the front runner in terms of off the shelf performance but - Need to check out the firewire chipset before purchase and it doesn't look like eSata is available

Dell would otherwise be interesting but tends to use the Ricoh chipset for firewire which is concidered to have poor performance - is there anybody here using one of these?

Lenovo -- lots of models that at least have an express card slot... Which models have people got that work ok with a firewire express card?

System76 some interesting possibilities talked to one of there guys, said they may take on my suggestion of providing a laptop with descent firewire.

everybody else

Either no firewire or problematic firewire chipsets, No express card slot. No real market differenciation.

Other suggestions?

Re: [LAU] Laptops for firewire based pro-audio on linux

Hi there,

I'm on a Macbook Pro (late 2010). Firewire is Agere, not TI!
I really was angry when I discovered this, as I was told by the Apple sales person that they work with TI. Apple continuously screw their customers with ever changing chipsets, despite knowing most of their customers are doing professional work with their macs.
Tried to run Ubuntustudio on the mac and having issues with xruns all over the place.
Other than that Macs are wonderful machines.

Warm regards,
Moshe

[LAU] Soundcard broken? What else can I test

Hello everyone!
   I had strange goings-on this morning. Yesterday night, I left some sound 
playing, which looked like it had finished allright. But on another console I 
saw, that a paused mplayer had some errors and wouldn't unpause again. I quit 
it and restarted. No luck, I discovered, that ALSA wasn't working properly.
   So I rebooted a couple of times. The first time, no Delta soundcard at all. 
I turned the computer off, felt, that the Delta was properly screwed in its 
place. Yep. Rebooted, found the soundcard.
   But the alsamixer settings were a bit wrong. The S/PDIFF items at thwe 
beginning were set to IEC958 in-l and r, although I'd ALWAYS left them sitting 
on pcm out. So were the "hw in" elements all set to the same in-l and in-r 
device. The internal clock was set to iec958 input and couldn't be changed, 
the default rate was set to 96000, which is always 48000.
   I rebooted and could changed the internal clock to 48000, I heard a pop, 
when I did it. Only after that, were aplay and mplayer -ao alsa,default 
showing movement. Before then, they started and paused at 0, unable to move 
forward.
   Still: No Sound! I can start my jack as well. All the volume levels are 
check. ALL, that I can see in the playback view.
   In jack I tried using mplayer - with -ao jack) and a direct connection of 
in/out ports of the card itself. No luck!
   So please, what else can I do, to eliminate possibilities, that would 
frighten me.
   Warmly yours
             Julien

Re: [LAU] paulstretch portaudio conflict

Hi all,

Thanks for your responses. Atte, I wasn't aware that there was a python version of the application, or that it would be relatively easy to set up - I did get that working, so thanks for the tipoff.

Robin - thanks also. With your suggestion I did get paulstretch to compile correctly. I had tried running ./compile_linux_fftw_jack.sh earlier, but hadn't twigged that deleting PAaudiooutput.cpp would fix the problem.

Thanks again! Now I'm off to do some extreme timestretching.

Compile it with JACK and without portaudio support:
./compile_linux_fftw_jack.sh

Note: the build-script compiles *.cpp - yet no function from
PAaudiooutput.cpp is used in the JACK version. Either fix the
build-script or simply mv PAaudiooutput.cpp PAaudiooutput.outoftheway

AFAIK Paul Nasca does still develop and maintain it.

The first FW643 revision was buggy, but the latest Lucent, er, Agere,
I mean, LSI chips (FW643E, FW533E) are actually better then TI chips.

It's hard to be sure what causes them, but it's unlikely to be the
controller.

Is your FireWire interrupt shared with other devices?  Are you using the
nvidia graphics driver?  Are you running something like NetworkManager
that scans for new networks?

Clemens

I was angry that I was told it was a TI chipset just to find out it was Agere.

The first FW643 revision was buggy, but the latest Lucent, er, Agere,
I mean, LSI chips (FW643E, FW533E) are actually better then TI chips.

It's hard to be sure what causes them, but it's unlikely to be the
controller.

Could be, didn't dig too deep on that matter as I simply use Ardour/Mixbus on OSx.

Is your FireWire interrupt shared with other devices? Are you using the
nvidia graphics driver? Are you running something like NetworkManager
that scans for new networks?

Interrupt- Didn't check.
Graphic driver- yes using nvidia
Network manager- yes

Just thought I would share my experience (also if it's not much).

Cheers
Moshe

This indicates a hardware problem with either the mainboard, the slot,
or the sound card.

This would be a symptom of some of the chip's registers not actually
working.

> All the volume levels are check.

Some mixer controls cannot be read from the hardware, so the driver just
reports the last value it has written.

> what else can I do, to eliminate possibilities

The only remaining possibility is the ICE1712 chip on the sound card.
It's busted.
