I really doubt it when looking * at the mixer register layout) * - builtin genuine OPL3 * - full duplex 16bit playback/record at independent sampling rate * - MPU401 (+ legacy address support) FIXME: how to enable legacy addr?? * - game port (legacy address support) * - built-in General DirectX timer having a 20 bits counter * with 1us resolution (FIXME: where is it?) * - I2S serial port for external DAC * - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI * - supports hardware volume control * - single chip low cost solution (128 pin QFP) * - supports programmable Sub-vendor and Sub-system ID * required for Microsoft's logo compliance (FIXME: where?) * - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms * * Certain PCI versions of this card are susceptible to DMA traffic underruns * in some systems (resulting in sound crackling/clicking/popping), * probably because they don't have a DMA FIFO buffer or so. * Overview (PCI ID/PCI subID/PCI rev.): * - no DMA crackling on SiS735: 0x50DC/0x1801/16 * - unknown performance: 0x50DC/0x1801/10 * * Crackling happens with VIA chipsets or, in my case, an SiS735, which is * supposed to be very fast and supposed to get rid of crackling much * better than a VIA, yet ironically I still get crackling, like many other * people with the same chipset. * Possible remedies: * - plug card into a different PCI slot, preferrably one that isn't shared * too much (this helps a lot, but not completely!) * - get rid of PCI VGA card, use AGP instead * - upgrade or downgrade BIOS * - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX) * Not too helpful. * - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS * * BUGS * - when Ctrl-C'ing mpg321, the playback loops a bit * (premature DMA playback reset?) * - full-duplex sometimes breaks (IRQ management issues?). * Once even a spontaneous REBOOT happened!!! * * TODO * - test MPU401 MIDI playback etc. * - power management (CONFIG_PM). See e.g. intel8x0 or cs4281. * This would be nice since the chip runs a bit hot, and it's *required* * anyway for proper ACPI power management. In other words: rest * assured that I *will* implement this very soon; as soon as Linux 2.5.x * has power management that's bugfree enough to work properly on my desktop. * - figure out what all unknown port bits are responsible for */ #include <sound/driver.h> #include <asm/io.h> #include <linux/init.h> #include <linux/pci.h> #include <linux/delay.h> #include <linux/slab.h> #include <sound/core.h> #include <sound/control.h> #include <sound/pcm.h> #include <sound/rawmidi.h> #include <sound/mpu401.h> #include <sound/opl3.h> #define SNDRV_GET_ID #include <sound/initval.h> #include "azt3328.h" MODULE_AUTHOR("Andreas Mohr <hw7oshyuv3001@sneakemail.com>"); MODULE_DESCRIPTION("Aztech AZF3328 (PCI168)"); MODULE_LICENSE("GPL"); MODULE_CLASSES("{sound}"); MODULE_DEVICES("{{Aztech,AZF3328}}"); #define DEBUG_MISC 0 #define DEBUG_CALLS 0 #define DEBUG_MIXER 0 #define DEBUG_PLAY_REC 0 #define DEBUG_IO 0 #define MIXER_TESTING 0 #if DEBUG_MISC #define snd_azf3328_dbgmisc(format, args...) printk(KERN_ERR format, ##args) #else #define snd_azf3328_dbgmisc(format, args...) #endif #if DEBUG_CALLS #define snd_azf3328_dbgcalls(format, args...) printk(format, ##args) #define snd_azf3328_dbgcallenter() printk(KERN_ERR "entering %s\n", __FUNCTION__) #define snd_azf3328_dbgcallleave() printk(KERN_ERR "leaving %s\n", __FUNCTION__) #else #define snd_azf3328_dbgcalls(format, args...) #define snd_azf3328_dbgcallenter() #define snd_azf3328_dbgcallleave() #endif #if DEBUG_MIXER #define snd_azf3328_dbgmixer(format, args...) printk(format, ##args) #else #define snd_azf3328_dbgmixer(format, args...) #endif #if DEBUG_PLAY_REC #define snd_azf3328_dbgplay(format, args...) printk(KERN_ERR format, ##args) #else #define snd_azf3328_dbgplay(format, args...) #endif #if DEBUG_IO #define snd_azf3328_dbgio(chip, where) \ printk(KERN_ERR "%s: IDX_IO_PLAY_FLAGS %04x, IDX_IO_PLAY_IRQMASK %04x, IDX_IO_IRQSTATUS %04x\n", where, inw(chip->codec_port+IDX_IO_PLAY_FLAGS), inw(chip->codec_port+IDX_IO_PLAY_IRQMASK), inw(chip->codec_port+IDX_IO_IRQSTATUS)) #else #define snd_azf3328_dbgio(chip, where) #endif static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; /* Index 0-MAX */ static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; /* ID for this card */ static int enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; /* Enable this card */ static int joystick[SNDRV_CARDS] = {-1}; /* "unset" as default */ MODULE_PARM(index, "1-" __MODULE_STRING(SNDRV_CARDS) "i"); MODULE_PARM_DESC(index, "Index value for AZF3328 soundcard."); MODULE_PARM_SYNTAX(index, SNDRV_INDEX_DESC); MODULE_PARM(id, "1-" __MODULE_STRING(SNDRV_CARDS) "s"); MODULE_PARM_DESC(id, "ID string for AZF3328 soundcard."); MODULE_PARM_SYNTAX(id, SNDRV_ID_DESC); MODULE_PARM(enable, "1-" __MODULE_STRING(SNDRV_CARDS) "i"); MODULE_PARM_DESC(enable, "Enable AZF3328 soundcard."); MODULE_PARM_SYNTAX(enable, SNDRV_INDEX_DESC); MODULE_PARM(joystick, "1-" __MODULE_STRING(SNDRV_CARDS) "i"); MODULE_PARM_DESC(joystick, "Forced joystick port enable for AZF3328 soundcard.
