| 28 | * NOTES |
| 29 | * Since Aztech does not provide any chipset documentation, |
| 30 | * even on repeated request to various addresses, |
| 31 | * and the answer that was finally given was negative |
| 32 | * (and I was stupid enough to manage to get hold of a PCI168 soundcard |
| 33 | * in the first place >:-P}), |
| 34 | * I was forced to base this driver on reverse engineering |
| 35 | * (3 weeks' worth of evenings filled with driver work). |

Andreas Mohr | 02330fb | 2008-05-16 12:18:29 +0200 | [diff] [blame] | 38 | * It is quite likely that the AZF3328 chip is the PCI cousin of the |
| 39 | * AZF3318 ("azt1020 pnp", "MM Pro 16") ISA chip, given very similar specs. |

| 42 | * for compatibility reasons) from Azfin (joint-venture of Aztech and Fincitec, |
| 43 | * Fincitec acquired by National Semiconductor in 2002, together with the |
| 44 | * Fincitec-related company ARSmikro) has the following features: |
| 45 | * |
| 46 | * - compatibility & compliance: |

Andreas Mohr | 13769e3 | 2006-05-17 11:03:16 +0200 | [diff] [blame] | 53 | * Note that "conformant" != "compliant"!! this chip's mixer register layout |
| 54 | * *differs* from the standard AC97 layout: |
| 55 | * they chose to not implement the headphone register (which is not a |
| 56 | * problem since it's merely optional), yet when doing this, they committed |
| 57 | * the grave sin of letting other registers follow immediately instead of |
| 58 | * keeping a headphone dummy register, thereby shifting the mixer register |
| 59 | * addresses illegally. So far unfortunately it looks like the very flexible |
| 60 | * ALSA AC97 support is still not enough to easily compensate for such a |
| 61 | * grave layout violation despite all tweaks and quirks mechanisms it offers. |

| 105 | * Oh, and make sure to unmute the FM mixer control (doh!) |
| 106 | * NOTE: power use during OPL3 playback is _VERY_ high (70W --> 90W!) |
| 107 | * despite no CPU activity, possibly due to hindering ACPI idling somehow. |
| 108 | * Shouldn't be a problem of the AZF3328 chip itself, I'd hope. |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 113 | * Certain PCI versions of this card are susceptible to DMA traffic underruns |
| 114 | * in some systems (resulting in sound crackling/clicking/popping), |
| 115 | * probably because they don't have a DMA FIFO buffer or so. |
| 116 | * Overview (PCI ID/PCI subID/PCI rev.): |
| 117 | * - no DMA crackling on SiS735: 0x50DC/0x1801/16 |
| 118 | * - unknown performance: 0x50DC/0x1801/10 |
Andreas Mohr | d91c64c | 2005-10-25 11:17:45 +0200 | [diff] [blame] | 119 | * (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler) |
| 120 | * |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 121 | * Crackling happens with VIA chipsets or, in my case, an SiS735, which is |
| 122 | * supposed to be very fast and supposed to get rid of crackling much |
| 123 | * better than a VIA, yet ironically I still get crackling, like many other |
| 124 | * people with the same chipset. |
| 125 | * Possible remedies: |
Andreas Mohr | 02330fb | 2008-05-16 12:18:29 +0200 | [diff] [blame] | 126 | * - use speaker (amplifier) output instead of headphone output |
| 127 | * (in case crackling is due to overloaded output clipping) |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 128 | * - plug card into a different PCI slot, preferrably one that isn't shared |
| 129 | * too much (this helps a lot, but not completely!) |
| 130 | * - get rid of PCI VGA card, use AGP instead |
| 131 | * - upgrade or downgrade BIOS |
| 132 | * - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX) |
| 133 | * Not too helpful. |
| 134 | * - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS |
