I have a Delfina Plus that is a real nice card. Uses no CPU and is very zorro bus friendly.
I have played with different libraries (4.14, 4.16. 4.16B, 4.17B), Delfmem, and Delfinit. I haven't found the magic combination to make it perfectly (or real close to it) stable yet.
I tried using AHI for playback as well as the delfmpeg.library for mp3.
Sometimes it plays for a real long time, even with the screen saver. The screensaver does seem to bugger up playback sometimes. Once in a while, it will just crash on playback without the screensaver.
I think I'm close, but was hoping to see what other delfina users are using for their settings and programs. As well as best practices.

LOL, these cards are clunky.
they always have been. always will be.

I had the flipper edition for my A1200 (desktop), worse Amiga experience ever (even worse than trying to fit a FastATA).
I only got it to output sound once and even then it sounded terrible ;)
Sold it now and I'm just sticking to good old Paula for my AHI playback. With the right utils you can remove most of the noise from 14bit Paula and get some awesome sound out of the original chipset (esp if you've also had your CAPS replaced). The need for MP3 playback is overrated these days because hard drive space is so cheap, I just rip all of my CDROM'S to uncompressed audio and play them back using AMP.
-
You're ahead of me. I never got the Flipper to work at all.

I use a MasPlayer these days. It's close enough to perfect for me.
-
I tried the Delfina a long time ago, as well as a clock port sound card. Gave up and sent them both back. Stable? Not once. Not an option for many people, but I use a USB sound card now and it's perfect (at least on my Deneb; I can't speak for other USB interfaces.)
-
Under 3.9 mine kep crashing after 20 min, sometimes after an hour.
The i reinstalled it with the latest libs, used the ones from a friend in poland, and since then it plays well with the mpega.library
The chips on the card are getting warm though so i put some alu coolers on them and an extra fan. Maybe that helped?
I can mail you the files if u want
, send me a pm with ur email

@midway
Thanks!
What programs and settings do you use?
PM my email. ..
I will check the chips for heat also.

Delfina in zorro slot will never run stable, because is no longer supported. It's a shame. I think you should sell it or wait that someone makes a stable driver. I think the sc is open source now.
-
Tried one years ago and it was the biggest nightmare I ever encountered.
Friend bought it and could never get it stable, so he let me try. I couldn't either, lol. He returned it to the shop for a refund.

I've never had Delfina Plus, but Delfina Lite with DSP changed to 66MHz version works very nice.

@Stachu
What do you use to play mp3's? (library versions, devices, etc). Does it crash? The plus is clocked at 73MHz from the factory.
@Midway
I think your onto something. I installed AmigaAmp and using the mpega.library and by golly, this seem to run perfectly so far. I will continue testing, but so far it is promising!!!

Mpega.library and amigaamp are perfect for play back.
Only issue is that it is a bit slow on my 060 and the plus.
-
I had the delfina lite also overclocked. It played ok for a few moments, but if I did another thing it would crash. Of course if you have a ppc, you can decode with no problems, and still use the ahi part of the card , then it won't crash.
I think it was a nice idea that didn't get the deserved support. Get yourself an AD516 with mas player or if you can get a prelude with mpegit, your problems will be over, as mine did :)

@marmes
I'm not ready to throw in the towel yet. I have a Melody Z2, I can switch to if need be. I think there is a way to get this pretty close to perfect...
-
The Delfina Flipper which I attached to a VarIO`s clockport and use through AmigaAMP runs stable.
I have been running it for up to 6 hours in a row (tonight only one hour) without issues. Using AMPlifier and the delfina.library looks different... sometimes it crashes after 20 minutes sometimes after an hour..
So I use AmigaAMP and it works !
I use mhimdev.library, 256 kb load buffer, play buffer 1sec
I have a CS MKI with 128 MB ram, SCSI module, and a subway usb card on a ISDN card which has a clockport for that one.
It took a little tinkering but this solution seems stable

I don't have Delfina anymore but if I remember correctly, the problem seemed to be in the DSP system software, in the multitasking / time-sharing part. It locked up very easily.
Disabling Delfina's Watchdog helped, but it didn't solve the problem.
You could try DelfTweak. You can increase DSP's internal clock cycles with it, which may help. I wrote it for Delfina Lite so I don't know how it actually affects on Delfina Plus. However, Delfina Lite and Plus have the same DSP so it should work.
-
Solved!!!
Thanks especially to Midway, Damion, and Matt_H (Damion and Matt had older threads that helped.)
It runs perfectly stable even WITH the screen saver running. I ran it for over 24 hours with a mix of mp2's and mp3's with BTD screen saver.
In the end, yes the Delfina was a bit of a pain to find the magic combo, but the card is simply awesome. Little CPU load, friendly on the zorro bus, and excellent sound quality.
Here was my winning combination:
AmigaAmp (Amplifier tends to crash over time). Latest 68K version from their website.
MHI
DelfinaMpeg Version: 1.6
Delfina.library Version 6.14 B3 Patch #2.
Delfinit NOPATCH Quiet - to init the card.
I used the same settings as Midway for Amigaamp 1s and 256k for playback settings.
Thanks again to all that helped!
Even though I use a Delfina Plus, I'm sure that this would work fine on a Lite also and maybe even the original Delfina zorro card. Have no idea if the clockport version will work well with my setup.

So the VarIO does have a clockport? It is unclear on the BBOAH. Does it work also with Subway and other devices?
-
Glad to hear you got it to work !
2 xanxi: yes, the VarIO has a clockport. If it works with the delfina it should work with the subway as well. Just remember to plug it in the right way !
