Rename es1370.c to es137x.c and merge in the patches to support

ES1371 and ES1373 PCI Audio Sound Chips. The 1371 and 1373 can be found on newer CreativeLabs/Ensoniq sound cards such as the SoundBlaster PCI 16,64 and 128. Submitted by: Russell Cattelan Obtained from: Parts obtained from linux, but rewritten by Russell

this is a full fix for writes not aligned to the sample size selected.

should be a no-op in most cases.

set default ogain to 50 since some sb cards produce no sound at 0

Fix a typo in the DRIVER_MODULE() declaration which caused a collision

1999-11-15T17:03:30Z

with the real mss module.

Remove duplicate entry for ADS7180 - it's meant to be handled by the

1999-11-15T17:02:32Z

forked-off ad1816 driver.

Remove some printfs and make it slightly more paranoid about accepting

that an ess1888 is present.

* Ignore the wierd fakechan workarounds for simplex in dsp_ioctl().

Without this, ioctl commands for setting formats and speeds were essentially ignored for simplex devices until the application actually performed a read or write. * Make sure that both channels are set in the SB mixer code and provide a mixer table specifically for the ess18xx which supports the extended accuracy available on this part. * Fix a stupid bug in ess_format() which ignored the passed-in format and changed the hardware based on the value which was set last time. This meant that the hardware setting was often not set correctly at all. * Add a custom identify driver for the ESS1888 which automagically detects and adds the device in a pseudo-PnP way. This driver also emits the magic sequence which enables the sound hardware after a hard reset, allowing it to work correctly for the sound hardware of a PWS 433au (and probably all other PWS class alpha machines). With these changes, I was able to play back simple sounds on my 433au. I have not tested recording or any other formats other than 8bit ulaw and 16bit stereo.

Conserve stereo mode in ioctl SNDCTL_DSP_SETFMT.
