ALS-007 based soundcards
========================
Support for soundcards based around the Avance Logic ALS-007 chip is
included. The ALS-007 is a single chip PnP sound solution which is mostly
hardware compatible with the Sound Blaster 16 card, with most differences
occuring in the use of the mixer registers. For this reason the ALS-007
code is integrated as part of the Sound Blaster 16 driver (adding only 800
bytes to the SB16 driver).
To use an ALS-007 soundcard under Linux, enable the following options in the
sound configuration section of the kernel config:
- 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support
- FM synthesizer (YM3812/OPL-3) support
Since the ALS-007 is a PnP card, the sound driver probably should be
compiled as a module, with the isapnptools used to wake up the soundcard.
Set the "I/O base for SB", "Sound Blaster IRQ" and "Sound Blaster DMA" (8 bit -
either 0, 1 or 3) to the values used in your particular installation (they
should match the values used to configure the card using isapnp). The
ALS-007 does NOT implement 16 bit DMA, so the "Sound Blaster 16 bit DMA"
should be set to -1. If you wish to use the externel MPU-401 interface on
the card, "MPU401 I/O base of SB16" and "SB MPU401 IRQ" should be set to
the appropriate values for your installation. (Note that the ALS-007
requires a separate IRQ for the MPU-401, so don't specify -1 here). (Note
that the base port of the internal FM synth is fixed at 0x388 on the ALS007;
in any case the FM synth location is not setable in the kernel config).
The resulting sound driver will provide the following capabilities:
- 8 and 16 bit audio playback
- 8 and 16 bit audio recording
- Software selection of record source (line in, CD, FM, mic, master)
- Record and playback of midi data via the external MPU-401
- Playback of midi data using inbuilt FM synthesizer
- Control of the ALS-007 mixer via any OSS-compatible mixer programs.
Controls available are Master (L&R), Line in (L&R), CD (L&R),
DSP/PCM/audio out (L&R), FM (L&R) and Mic in (mono).

Getting Firmware
~~~~~~~~~~~~~~~~
See the end of this document on how to obtain and create the necessary
firmware files.
Supported Features
~~~~~~~~~~~~~~~~~~
Currently digital audio and mixer functionality is supported. (memory
mapped digital audio is not yet supported). MultiSound support is
fully modularized, and can only be used as modules:
msnd - MultiSound base (requires soundcore)
msnd_classic - Base audio/mixer support for Classic, Monetery and
Tahiti cards
msnd_pinnacle - Base audio/mixer support for Pinnacle and Fiji cards
Important Notes - Read Before Using
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The firmware files are not included (may change in future). You
must obtain these images from Turtle Beach (they are included in the
MultiSound Development Kits), and place them in /etc/sound for
example, and give the full paths in the Linux configuration. Please
note these files must be binary files, not assember.
* You need the following information to use this driver: the card's
I/O base (i.e. 0x250), the IRQ (i.e. 5), and the shared memory area
(i.e. 0xd8000).
* Probing is not currently implemented, and only the msnd_classic
driver will actually program the card's IRQ and SMA locations; the
msnd_pinnacle is primarily for use with the card in PnP mode, however
it should work if you know what the card's resource values are (this
will change in the future).
* Note the Turtle Beach Pinnacle card contains a Kurzweil MA-1
synthesizer with an MPU compatible interface, which should work with
the mpu401 module. You must know the resource values of the MA-1.
Examples
~~~~~~~~
* If you have a MultiSound Classic/Monterey/Tahiti:
insmod soundcore
insmod msnd
insmod msnd_classic io=0x290 irq=7 mem=0xd0000
* If you have a MultiSound Pinnacle:
insmod soundcore
insmod msnd
insmod msnd_pinnacle io=0x210 irq=5 mem=0xd8000
* To use the MPU-compatible Kurzweil synth on the Pinnacle, add the
following:
insmod sound
insmod mpu401 io=0x330 irq=9
msnd_classic, msnd_pinnacle Required Options
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If the following options are not given, the module will not load.
Examine the kernel message log for informative error messages.
WARNING--probing isn't supported so try to make sure you have the
correct shared memory area, otherwise you may experience problems.
io I/O base of DSP, e.g. io=0x210
irq IRQ number, e.g. irq=5
mem Shared memory area, e.g. mem=0xd8000
msnd_classic, msnd_pinnacle Additional Options
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fifosize The digital audio FIFOs, in kilobytes. The default is
64kB (two FIFOs are allocated, so this uses up 128kB).
calibrate_signal Setting this to one calibrates the ADCs to the
signal, zero calibrates to the card (defaults
to zero).
Creating and Obtaining Firmware
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For the Classic/Tahiti/Monterey
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Download to /tmp and unzip the following file from Turtle Beach:
ftp://ftp.tbeach.com/pub/tbs/pinn/msndvkit.zip
When unzipped, unzip the file named MsndFiles.zip. Then copy the
following firmware files to /etc/sound (note the file renaming):
cp DSPCODE/MSNDINIT.BIN /etc/sound/msndinit.bin
cp DSPCODE/MSNDPERM.REB /etc/sound/msndperm.bin
When configuring the Linux kernel, specify /etc/sound/msndinit.bin and
/etc/sound/msndperm.bin for the two firmware files.
For the Pinnacle/Fiji
~~~~~~~~~~~~~~~~~~~~~
Download to /tmp and unzip the following file from Turtle Beach (be
sure to use the entire URL; some have had trouble navigating to the
URL):
ftp://ftp.tbeach.com/oldpub/tbs/pinn/pnddk100.zip
Put the following lines into a file named conv.l (between the start
and end lines):
-- conv.l start --
%%
[ \n\t,\r] ;
\;.* ;
DB ;
[0-9A-Fa-f]+H { int n; sscanf(yytext, "%xH", &n); printf("%c", n); }
-- conv.l end --
Then, compile the conv program with GNU make with the following
command:
make LEX=flex LOADLIBES=-lfl conv
This should give you an executable named conv. Now, we create the
binary firmware files by doing the following conversion (assuming the
archive unpacked into a directory named PINNDDK):
./conv < PINNDDK/dspcode/pndspini.asm > /etc/sound/pndspini.bin
./conv < PINNDDK/dspcode/pndsperm.asm > /etc/sound/pndsperm.bin
The conv (and conv.l) program is not needed after conversion and can
be safely deleted. Then, when configuring the Linux kernel, specify
/etc/sound/pndspini.bin and /etc/sound/pndsperm.bin for the two
firmware files.

HP300 notes
-----------
The Linux/HP web page is at <http://www.tazenda.demon.co.uk/phil/linux-hp/>
Currently only 9000/340 machines have been tested. Any amount of RAM should
work now but I've only tried 16MB and 12MB.
The serial console is probably broken at the moment but the Topcat/HIL keyboard
combination seems to work for me. Your mileage may vary.
The LANCE driver works after a fashion but only if you reset the chip before
every packet. This doesn't make for very speedy operation.
