+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).
