es1869 as sb?

es1869 as sb?

[Kasper Souren]

Hi. I'm trying to get my laptop soundchip, an ES1869 running under ALSA. 
Under OSS it runs as an sb. With "modprobe sb io=0x220 irq=5 dma=1 dma16=5" 
I get:

SB 3.01 detected OK (220)
ESS chip ES1869 detected
<ESS ES1869 AudioDrive (rev 11) (3.01)> at 0x220 irq 5 dma 1,5

But this doesn't work with any of the ALSA sb modules. None of them accepts 
  any of the parameters I supply to in the command above. Is there a way to 
supply IRQ and DMA settings?
Or is there another way to get it running?

And also the ALSA es18xx module doesn't work. But I expected that, since I 
didn't manage to get the OSS es18xx module to work. But maybe I can help 
supporting the 1869 under the es18xx module. I'd be happy to do that.

greetz,
Kasper

sb driver on alsa doesn't support es18xx chipset.  it is supported by
es18xx module.

isn't it pnp chip?
if not, generally, you have to set snd_isapnp=0 option together with
irq and ioports specifications.

well, es18xx might be broken, as already posted.
unfortunately we cannot test it because of lack of hardware.
it'd be apprecated if you help debugging, then.

I was sent some information about how to get it running. Probably I didn't 
go through the manuals thoroughly. But up to now I haven't had time to 
figure it out. I'll start reading more about alsa, and will enable 
debug-support.

I also have a laptop that has an ESS ES1879 AudioDrive, and could get ALSA to
work. I posted a question/request to this list about 6 weeks ago as well, but
never even got a response back.I gave up and went back to OSS.

I hope you have more luck! Maybe, if you get the ES1869 problem solved, it'll
fix the ES1879 as well! :-)  I wouldn't think that the ALSA developement team
would want to keep around a broken driver.

For now, the es18xx is broken. In the source code you can find the following 
commentary:

/* GENERAL NOTES:
 *
 * BUGS:
 * - There are pops (we can't delay in trigger function, cause midlevel
 *   often need to trigger down and then up very quickly).
 *   Any ideas?
 * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
 */

/*
 * ES1868  NOTES:
 * - The chip has one half duplex pcm (with very limited full duplex support).
 *
 * - Duplex stereophonic sound is impossible.
 * - Record and playback must share the same frequency rate.
 *
 * - The driver use dma2 for playback and dma1 for capture.
 */

/*
 * ES1869 NOTES:
 *
 * - there are a first full duplex pcm and a second playback only pcm
 *   (incompatible with first pcm capture)
 *
 *
 * - there are a first full duplex pcm and a second playback only pcm
 *   (incompatible with first pcm capture)
 *
 * - there is support for the capture volume and ESS Spatializer 3D effect.
 *
 * - contrarily to some pages in DS_1869.PDF the rates can be set
 *   independently.
 *
 * BUGS:
 *
 * - There is a major trouble I noted:
 *
 *   using both channel for playback stereo 16 bit samples at 44100 Hz
 *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
 *
 *   The same happens using Audio1 for captureing.
 *
 *   The Windows driver does not suffer of this (although it use Audio1
 *   only for captureing). I'm unable to discover why.
 *
 */

so oss sb is for now the only driver that work :-(
