Software News   Software News : New emu10kx and CMI8738 drivers and new Mixer
   posted by DaveAE on 19-Sep-2005 20:38:31 (8831 reads)
Recently uploaded to OS4depot:

- emu10kx v6.2: This may solve the freezes that people experienced when playing sound together with using ethernet (eth3com). People have transferred several GB of data without a freeze, so it is looking good. An IRQ timer that was set to generate 1000 interrupts per second was changed to 80Hz. It seems that the VIA686B PIC isn't too happy about handling many IRQ's/second.



- CMI8738 v5.12: Can solve some sound crackle issues, especially after Grim Reapers and other situations where only a stop and start of playback could 'solve' the crackling.

- Mixer v1.15: Daniel Westerberg has added extensive ARexx support to Mixer and solved some bugs. Please read the accompanying ARexx.readme for more information.

Kind regards,

Davy Wentzler

@Davy,

This is the BEST news we have had at AW in ages!
Thank you for all your intensive work with audio.

Best Wishes,

Good news for all SB Live! users out there! I upgraded to a Terratec from the SB Live! a while back because of the very "issues" with the SB Live!.

@all

Well, I put "may " in bold.

@Samwel
Well, there are some unexplained issues on the microA1 left. The CMI driver will show lost and delayed irq's on serial debug, and IBrowse seems to cause them a lot, while AWebPPC doesn't.
But overall, I would say it's getting better.

IMPORTANT
Currently it looks like the mixer and emu10k driver listed on OS4depot are still the older versions. The CMI8738 driver is the newer one, however.

Whatever you finally dig up on this IRQ issue will contribute to the overall stability of OS4. This IRQ issue could be hardware, firmware, or OS4. But at least you have exposed the issue and theoretically someone will come up with "the answer".

Thanks for all your work.

@Davy

Good to hear! Thanks for all your hard work on this.

Btw the MIC boost tool you made for the CMI driver, couldn't this be incorporated
into the MIxer instead as a checkbox option? Would be alot more professional
IMHO.

EDIT: Have you checked with Stefan Burstroem about this problem with IBrowse?
Also as a OS4 beta tester you have access to IBrowse 2.4 beta also have you not?
So does this version still have problems with the IRQ's or is it bound to 2.3?

well _THIS_ is one news item i've been waiting for since ages!!!
i just hope it works well! Maybe it will make my inet connexxxion a bit more stable, i sure hope so. being able to listen to music on my a1 aint, well haha, it ain't bad either. guess you would expect to be able to do that from the moment of purchase, but but.. mumble mumble.. GREAT WORK DAVE!
This might eliminate 50% of the network lockups for me. Eagerly awaiting a new ethernet device. Does anyone know if (when finished) the ethernet driver will be uploaded to OS4 depot, or if we will have to wait until 'around x-mas sometime hopefully' ? :)

Hmm ... i spit out a lot more text than I intended, i just wanted to express my gratidude!

Great work Dave. Hope that the "maybe" will be, "works great".

Not so scary when you know he help out Davy test the driver..
This bug fix have been atleast a couple of weeks in the making with
several people involved.

All this started with Umisef making a comment about the sound problem
sounding just the same as they had on Amithlon. A buffer alignment
problem. Davy tested this and it didn't work fully, just a little better.
There seemed to be some kind of problem still. Like a bug in the hardware
or something. Now a week later Davy has made this release in which a
IRQ problem has been found.
Simply great work of all involved.

All- looks like drivers are now updated at OS4Depot.net replacing the older ones for emu10k and mixer.

The GUI is auto-generated according to the soundcard. Adding an optional checkbox option is possible, but makes it complicated (layout etc.). Anyway, it should always be on IMHO.

No, not yet.

IIRC, it still has problems.

@spotUP
You don't need a new ethernet (eth3com) device, you need the new emu10kx driver which is now on OS4depot, that is, if you have a emu10kx based soundcard.

This is great! I downloaded both the new mixer and the new Emu10kx v6.2 driver
(but getting my new TerraTec Aureon 7.1 Space by the end of the week!).

Thanks for the great work, Dave!

@Davy



The LineIn of the sound map with the new emu10kx.audio version 6.2 does not function yet. With version 5.16 it goes however. Still one fixes?
