Incorrect mixer controls on nVidia HDA MCP61 audio + Analog Devices AD1988 mixer

[losepete]

uniaud191_1922 report

Hardware: nVidia HDA MCP61 audio + Analog Devices AD1988 mixer

Installed the uniaud*.sys drivers and rebooted

No looping Startup sound.

smplayer still works, vlc - no sound.

Klondike Solitaire plays very slowly - not sure if this is uniaud related but with the uniaud drivers usually in use here this game is much quicker.

os2chess crashed after several minutes use - may or may not be related to uniaud drivers.

I needed to reboot due to the os2chess crash and it took 3 attempts before getting the system booted without looping startup sounds.

This is actually a big improvement over the uniaud_1922 supplied with eCS2.0GA which *never* booted without looping startup sounds but is not as good as the drivers usually in use here, uniaud16.sy from 114rc6 and uniaud32.sys from uniaud32_192, which very rarely suffer from the looping startup sounds problem - the most reboots needed is *1* if looping sounds occur.

Possibly of interest: Reading the Control ID list obtained by this command

unimix -list > ad1988.txt

Shows Control ID to be incorrect:-

The [Headphone Playback Volume] should be Control ID 3 but is in fact missing from the Control ID list. All Control IDs from 3 inclusive are therefore incorrect.

uniaud 1.9.2 is the *last* build of uniaud that got that right:-

I have now reverted to the uniaud builds mentioned above as they work better.

The IRQ used by uniaud when using either uniaud191_1922 or the working drivers is IRQ11 which is not shared with any other device.

Repeating system sounds is not a uniaud issue. The mixer control issue is known and we intend to address it. Ticket summary changed to reflect the mixer issue.
