Poseidon compatible USB Sound Card

[Moto]

Hello my fellow Amiga Brethren,

Can somebody tell me what USB sound cards are compatible with the Deneb/Subway USB controllers?  I have spent a good week searching for this answer but can't really find a definitive source of what works and what doesn't.  I have an old M-Audio Sonica and I plugged it in and it was immediately not recognized.  I see lots of $10 usb sound cards on Amazon (C-media chipset) but I don't want to buy something unless I know it works.  I'd love to be able to listen to some cleaner audio (mp3s, etc) on the Amiga.

Thanks in advance!

PS:  I have a "new" old stock 4000T arriving today!  Will post a slide show if I can get my camera working.

I was under the impression they all worked...  Hmmmm.....

I assume it's an AT model?  If it's a CBM one its gotta be worth a few grand!!

I'm not expecting a CBM model but I'll let you know if that's the case.

Is there a standard for all USB sound cards?  I've been through all the Poseidon docs and I didn't see any kind of compatibility list at all.

To answer my own question, it seems there is a standard.  It's called USB audio device specification 1.0 -- so I imagine that the Poseidon stack will work with any of these devices.  I wish the documentation simply stated this.

Can anyone confirm this?  I can get one of the vanilla cards for about $3.50

At that price, I'd risk it.

Actually, it shouldn't even have to be a typical sound card. Every external USB DAC, even an AV receiver with USB in for example, should be compatible with the said standard.

USB audio is only available for the Deneb. It will not work with the Highway, Algor or Subway controllers. There are two USB audio standards 1.x and 2.x (independent of the USB protocol version), which are not backwards compatible and only USB audio 1.x devices are supported. USB Audio 2.x devices are very very rare in fact.

What do you mean by "was immediately not recognized". This is not very helpful at all. PsdErrorlog/PsdDevlister? The AHI driver generated only supports mono/stereo at any bit rates between 8 and 32 bit per sample, but not multichannel modes and only rates up to 65KHz (because AHI uses a 16-bit word for frequencies :-( ).

If the soundcard does not offer such a PCM 8-32 bit mode at frequencies lower than 65 KHz, there's nothing much that can be done about it on the Amiga side. Most cheap USB soundcards do though.

I've been using a Creative Labs SoundBlaster X-fi with great results. This is a nicer external sound card with a lot of features. Some not even supported under AmigaOS, but it offers a superior s/n ratio and smoother sound I'd imagine than you'd get from a cheapie sound card.

I bought a $3 USB sound 'card' on Ebay and it seems to work fine with a Deneb in my A3000 using AHI

[Moto]

Yeah, there's a million of these things on amazon.  I got mine for 3.79 with free shipping.  

I saw the higher end ones on there such as Turtle Beach and Creative Labs but I figure I'd start low.  Besides even the cheapest one of these will sound much better than the poor Paula (for MP3s).  

BTW:  Amiga 4000T came in!  It's Smmmmminty new in the box but not a CBM model. I've taken pictures but I suddenly have a lot of work to do, so will post them later.  It's literally sitting next to me right now (almost as big as a person).

From DiscreetFX? You lucky son of a rat bastard!  lol

I got a 2 dollar one from DealXtreme, haven tried it yet though.

You should buy one that have good audio quality though, many reviewers on DX mentioned some chepie USB soundcards sounded bad.

Hi Chris, Quoting:

"USB audio is only available for the Deneb. It will not work with the Highway, Algor or Subway controllers." Bummer - I've got a Highway

Is this due to FlashRom requirements, CPU overhead, memory availablilty or something else? Wondering if a software-based 'usbaudio.audio' file could be written just as AHI typically seeks within its' root archives. If so, how would someone go about creating one?

[alexh]

Id guess at bandwidth. The Deneb has Zorro III bandwidth for RAW audio and the Subway only has clockport bandwidth.

But just a guess.

I've got several Creative Soundblaster Live cards that I hope will work with my Deneb + AHI
