I'm trying to get audio working on an Acer Travelmate 5720 laptop with Intel HDA (ICH8?) and Realtek ALC268 mixer.
I have tried various uniaud builds and am currently using uniaud195-1924-v2
All drivers tested seem to load at boot displaying something like HDA Intel at xxxxxx IRQ11 - where xxxxxx is some sort of address?
None of the drivers tested play any system sounds - yes System Sounds are Enabled and a Scheme is selected.
Using this command in the \mmos2 directory
unimix -list > uniaud_cntrls.txt
creates a list of Control IDs and shows their state.
Control ID1 has the Name: [Speaker Playback Volume] which has Count of values: 2; both values show as 0
I used unimix to try to turn these on:
unimix -id1 -cnt0 -val64
unimix -id1 -cnt1 -val64
Both attempts gave a success message and sound seems to play fine; the following command shows both speakers active
unimix -list > unitest.txt
Both vlc and (s)mplayer seem to work OK.
A little later I had to reboot and "lost" sounds again. I ran unimix -list > unitest2.txt and both speakers had been reset to 0.
I guess I need to set the speaker playback volume values at every boot. What is the best way to go about this?
Well, the easy answer is to create a CMD file with the above unimix commands to set volume and put a shadow of the CMD file in the Startup folder.
Another alternative would be to put the commands in startup.cmd in the root of the boot drive. |
