让SigmaTel STAC9227前置音频插孔工作
我在英特尔DG965RY上运行Ubuntu 10.10。 我的前置音频端口在Ubuntu中不起作用，后置音频端口不起作用。 当我使用Ubuntu 10.04时，我从来没有让它工作过，但这次我要再试一次。
我的编解码器是SigmaTel STAC9227
我的ALSA信息在这里 。
方便的细节：
!!ALSA Version !!------------ Driver version: 1.0.23 Library version: 1.0.23 Utilities version: 1.0.23 !!Loaded ALSA modules !!------------------- snd_hda_intel snd_hda_intel 我知道我必须更改模块的模型才能使前置音频插孔工作，但我在ALSA配置文件中找不到与模型相关的行 – /etc/modprobe.d/alsa-base.conf（我能够在Ubuntu 10.04中达到这一点，可能会有所改变。
我怎么能从这里开始？
编辑：模块详细信息：
Module snd-hda-intel -------------------- Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8, ICH9, ICH10, PCH, SCH), ATI SB450, SB600, R600, RS600, RS690, RS780, RV610, RV620, RV630, RV635, RV670, RV770, VIA VT8251/VT8237A, SIS966, ULI M5461 [Multiple options for each card instance] model - force the model name position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF) probe_mask - Bitmask to probe codecs (default = -1, meaning all slots) When the bit 8 (0x100) is set, the lower 8 bits are used as the "fixed" codec slots; ie the driver probes the slots regardless what hardware reports back probe_only - Only probing and no codec initialization (default=off); Useful to check the initial codec status for debugging bdl_pos_adj - Specifies the DMA IRQ timing delay in samples. Passing -1 will make the driver to choose the appropriate value based on the controller chip. patch - Specifies the early "patch" files to modify the HD-audio setup before initializing the codecs. This option is available only when CONFIG_SND_HDA_PATCH_LOADER=y is set. See HD-Audio.txt for details. beep_mode - Selects the beep registration mode (0=off, 1=on, 2= dynamic registration via mute switch on/off); the default value is set via CONFIG_SND_HDA_INPUT_BEEP_MODE kconfig. [Single (global) options] single_cmd - Use single immediate commands to communicate with codecs (for debugging only) enable_msi - Enable Message Signaled Interrupt (MSI) (default = off) power_save - Automatic power-saving timeout (in second, 0 = disable) power_save_controller - Reset HD-audio controller in power-saving mode (default = on) This module supports multiple cards and autoprobe. See Documentation/sound/alsa/HD-Audio.txt for more details about HD-audio driver. Each codec may have a model table for different configurations. If your machine isn't listed there, the default (usually minimal) configuration is set up. You can pass "model=" option to specify a certain model in such a case. There are different models depending on the codec chip. The list of available models is found in HD-Audio-Models.txt The model name "genric" is treated as a special case. When this model is given, the driver uses the generic codec parser without "codec-patch". It's sometimes good for testing and debugging. If the default configuration doesn't work and one of the above matches with your device, report it together with alsa-info.sh output (with --no-upload option) to kernel bugzilla or alsa-devel ML (see the section "Links and Addresses"). power_save and power_save_controller options are for power-saving mode. See powersave.txt for details. Note 2: If you get click noises on output, try the module option position_fix=1 or 2. position_fix=1 will use the SD_LPIB register value without FIFO size correction as the current DMA pointer. position_fix=2 will make the driver to use the position buffer instead of reading SD_LPIB register. (Usually SD_LPIB register is more accurate than the position buffer.) NB: If you get many "azx_get_response timeout" messages at loading, it's likely a problem of interrupts (eg ACPI irq routing). Try to boot with options like "pci=noacpi". Also, you can try "single_cmd=1" module option. This will switch the communication method between HDA controller and codecs to the single immediate commands instead of CORB/RIRB. Basically, the single command mode is provided only for BIOS, and you won't get unsolicited events, too. But, at least, this works independently from the irq. Remember this is a last resort, and should be avoided as much as possible... MORE NOTES ON "azx_get_response timeout" PROBLEMS: On some hardwares, you may need to add a proper probe_mask option to avoid the "azx_get_response timeout" problem above, instead. This occurs when the access to non-existing or non-working codec slot (likely a modem one) causes a stall of the communication via HD-audio bus. You can see which codec slots are probed by enabling CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec proc files. Then limit the slots to probe by probe_mask option. For example, probe_mask=1 means to probe only the first slot, and probe_mask=4 means only the third slot. The power-management is supported.

不幸的是，我没有太多想法让它们使用。
更新：
我尝试了为我的编解码器列出的每个模型，但仍然无法使其工作。
options snd-hda-intel model=ref options snd-hda-intel model=ref-no-jd options snd-hda-intel model=3stack options snd-hda-intel model=5stack options snd-hda-intel model=5stack-no-fp options snd-hda-intel model=dell-3stack options snd-hda-intel model=dell-bios options snd-hda-intel model=volknob options snd-hda-intel model=auto
我把它放在配置文件的末尾逐个尝试
sudo gedit /etc/modprobe.d/alsa-base.conf
每次改变后，我强行重装alsa
sudo alsa force-reload
我对SigmaTel STAC9227完全相同（尽管我的主板是DQ965GF）。 我设法让一个前端音频端口工作 – 麦克风。 它在我应用’3stack’选项后开始工作。 但您需要更改“声音首选项”>“输入”>“连接器”中的设置应设置为“麦克风2”。 但是我无法使前置音频输出与你所述的任何选项一起使用。 我想我必须深入研究解决方案:(
