SigmaTel STAC9250 @ Intel 82801GBM ICH7-M - High Definition Audio. High Definition Audio Controller B-0 PCI Free. STAC9250 @ Intel. Hello, I'm looking for Intel 82801GBM ICH7-M - High Definition Audio Controller sound drivers. Problem is there, when Windows 7 installs them, they are working, but not right. There is a problem, when I plung in headphones, laptop speakers doesn't mute.

Home (ICH7-M DH) • Intel® 82801GU ICH7-U Ultra Mobile (ICH7-U) Section 1.2 provides high-level feature differences for the ICH7 Family components. Note: Throughout this datasheet, ICH7 is used as a general ICH7 term and refers to the 82801GB ICH7, 82801GR ICH7R, 82801GDH ICH7DH, 82801GBM ICH7-M, 82801GHM ICH7-M DH, and 82801GU ICH7-U components, unless specifically noted otherwise. Note: Throughout this datasheet, the term “Desktop” refers to any implementation, be it in a desktop, server, workstation, etc., unless specifically noted otherwise. Note: Throughout this datasheet, the terms “Desktop”, “Digital Home” “Mobile”, and “Ultra Mobile” refer to the following components, unless specifically noted otherwise: • Desktop refers to the 82801GB ICH7, 82801GR ICH7R, and 82801GDH ICH7DH. • Digital Home refers to the 82801GDH ICH7DH and 82801GHM ICH7-M DH. • Mobile refers to the 82801GBM ICH7-M and 82801GHM ICH7-M DH. • Ultra Mobile refers to the 82801GU ICH7-U. This datasheet assumes a working knowledge of the vocabulary and principles of PCI Express*, USB, IDE, AHCI, SATA, Intel® High Definition Audio (Intel® HD Audio), AC ’97, SMBus, PCI, ACPI, and LPC. Although some details of these features are described within this manual, refer to the individual industry specifications listed in Table 1-1 for the complete details.

Reference Manual: Intel® High Definition Audio
Intel® I/O Controller Hub 7 (Intel® ICH7)/ Intel® High Definition Audio (Intel® HD Audio)/ AC’97: Programmer’s Reference Manual (PRM) For the Intel® 82801GB ICH7 and 82801GR ICH7R I/O Controller Hubs The Intel® HD Audio controller resides in PCI Device 27, Function 0 on bus 0. This function contains a set of DMA engines that are used ...to move samples of digitally encoded data between system memory and external codecs. Note: All registers in this function (including memory-mapped registers) must be addressable in byte, word, and DWord quantities. The software must always make register accesses on natural boundaries (i.e. DWord accesses must be on DWord boundaries; word accesses on word boundaries, etc.) In addition, the memory-mapped register space must not be accessed with the LOCK semantic exclusive-access mechanism. If software attempts exclusive-access mechanisms to the Intel® HD Audio memory-mapped space, the results are undefined. Note: Users interested in providing feedback on the Intel® HD Audio specification or planning to implement the Intel® High Definition Audio specification into a future product will need to execute the Intel® High Definition Audio Specification Developer’s Agreement.
