~pcwiz Posted July 21, 2008 Share Posted July 21, 2008 It seems that AD1988b audio and ALC889A audio share the exact same device ID. Take a look, here is the LSPCI line for ALC889A: 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 02) And here is the line for AD1988b audio: 00:1b.0 Audio device [0403]: Intel Corporation HD Audio Controller [8086:293e] (rev 02) They have the exact same device ID and everything! So I thought, if they are the same device, ALC889A drivers should work for AD1988b right? Wrong. ALC889A drivers don't work with it, so there is some difference. Can anyone shed any light on this? This is a problem, cause my tool that auto detects, downloads, and installs drivers for devices uses device ID detection, and it ends up installing ALC889A drivers for AD1988b.

Thanks That's the device ID for the Intel HD Audio Controller built into the chipset. The device IDs for the Analog Devices codecs are completely different. For one thing, the vendor ID 8086 has absolutely nothing to do with Analog Devices. My guess is the auto detect tool is incorrectly detecting the actual audio codec chip.

~pcwiz Posted July 30, 2008 Author Share Posted July 30, 2008 Yeah, the tool uses lspci detection, and lspci detects any audio codecs that are on the same bus as the same dev ID, basically its detecting the controller not the codec. 8086 is the vendor ID for Intel Link to comment https://www.insanelymac.com/forum/topic/116829-alc889a-and-ad1988b-share-same-device-id/#findComment-839303 Share on other sites More sharing options...
codylo Posted August 23, 2008 Share Posted August 23, 2008 I have some more experience on the installation of the ALC889a sound device on the Gigabyte P35-DS3R board. I was assumed the sound glitches problem was solved by the default installation of Kalyway 10.5.2. After used for a few days, I have tried to update with the Kalyway's 10.5.3 combo update and kernel update. I followed the readme instruction to install the combo update, don;t restart then install the kernel update. I don't know which kernel to choose during the kernel update so I just choose the one "original from Apple". After that, the sound glitches comes back! Sound from the VLC during video playback glitches and quit after a while. I then try to update the kernel again but this time I choose the "modbin_kernel_9.3" as shown in the attached. After reboot, the sound works perfectly again! I think this might also work with Leo4All as well but I have no time to test now, perhaps I will try to test on that later. The problem seems to be the compatability issue between the sound driver and the kernel.
