Trying to understand unimix.exe

[Martin Iturbide]

Hi

I'm doing some test of ArcaOS 5.0.5 on the Asus_B150_PRO_Gaming/Aura mainboard.

With the included Uniaud driver, sound works, but I have no volume control. It is set to an specific level and I can not raise it or lower it with the include volume control or "System Master Audio Volume ". PMUnimix just crash on startup.
Also the front jack headphones works (at the same time of the back jack), but it is too loud for the headset.

I have the following unimix.exe report:

Unimix -card

Any tip on how to control the volume on the Intel audio device? I guess it is dev0. Are the "id" or "Control ID" the different outputs (jacks or HDMI) of the audio adapter?

How is uniaudio driver loaded  ?  (I could read 2 adapters !)
- try
DEVICE=C:\MMOS2\UNIAUD32.SYS /A:1

Hi

I'm doing some test of ArcaOS 5.0.5 on the Asus_B150_PRO_Gaming/Aura mainboard.

I have the following unimix.exe report:

Unimix -list

Create a file named (for example) volumecontrol.cmd with contents

unimix -id3 -cnt0 -val%1 -cnt1 -val%1

and call it with (for example)

volumecontrol 44

Possibly you may also need to follow Remy's suggestion to use the switch /A:1 in your config.sys.

Hi Martin

Try Pauls later versions of uniaud to see if more controls become available - these show more controls on my system http://smedley.id.au/tmp/uniaud32-linux-3.5.zip

Other builds are available within this discussion https://www.os2world.com/forum/index.php/topic,2436.0.html

Thanks for the feedback.

Since I have limited access to that computer I will keep testing it on the weekend.

1) I will try unixmix tweeking the id3 as suggested.

unimix -id3 -cnt0 -val%1 -cnt1 -val%1

and call it with (for example)

volumecontrol 44

2) About:  "DEVICE=C:\MMOS2\UNIAUD32.SYS /A:1"
I guess I have two audio adapters, The first one is the Intel, and the second that does not get recognized I guess is the NVidia card audio output (via HDMI), which is attached to the mainboard.

According to the unimix reports it looks to me that "0" is the Intel and "1" may be the Nvidia. Am I guessing right?
I currently have audio on the Intel device, so I'm not sure if I should put it as "DEVICE=C:\MMOS2\UNIAUD32.SYS /A:1"

3) If the first options does not work to control the volume, I will try Paul's driver. And eve if it works I will try Paul's driver too.

Hi. Finally I got some time and computer time to try this. Also, now I even think I have a solid dual boot Win10/ArcaOS on this machine.

Create a file named (for example) volumecontrol.cmd with contents

unimix -id3 -cnt0 -val%1 -cnt1 -val%1

and call it with (for example)

volumecontrol 44

Tom, I tried your suggestion. It shows me an error but it reduced the volume to "44".

Here it is the error:

Code: [Select]

[C:\]unimix -id3 -cnt0 -val44 -cnt1 -val44

Setting Adapter: 0, ID:3, cnt:0, val:44...Success
Setting Adapter: 0, ID:3, cnt:1, val:44...Success

Everything works to the "87" value, if I go 88 or higher I get a different error.

Code: [Select]

Setting Adapter: 0, ID:3, cnt:1, val:88...Failed

It is a good progress, but I will keep trying the other options.

I will keep testing.

Hi

I used:

DEVICE=C:\MMOS2\UNIAUD32.SYS /A:1

Rebooted and produced no sound to me.

I change it to:

DEVICE=C:\MMOS2\UNIAUD32.SYS /A:0

Rebooted and source got back again.

The rexx script "volumecontrol 44" also works and no longer gave me the "Error: invalid number of PCM instances for adapter 1"

I guess it is good.  I will try Paul's latest driver next.

Thanks for the feedback.

I just tried this Uniaud version using the same "DEVICE=C:\MMOS2\UNIAUD32.SYS /A:0"
Sound works, but I had lost volume control with unimix.

The maximum value to be used is 87, hence trying to set the volume to 88 fails.
(that maximum is listed in your earlier post that showed the output of unimix -list)

Try again unimix -list and search the output for "Master Playback Volume". Which id does it have?
If it is (for example) id2, then in volumecontrol.cmd change id3 into id2 and see if volume control works again this way.

Hi Tom

With Paul's driver, it seems it is also ID3

I no longer have volume control with unimix.

If I revert to the older driver ( 2.02.06 / 6 May 2020 14:21:32) I got back the volume control with unimix.

Are there just the 3 IDs or did you truncate it at Master Playback Volume?
I have to set Master Playback Volume and Speaker Volume (there is also a Headset volume).  Both Master and Speaker Volumes changed IDs under Paul's latest build.  Speaker then defaulted to 0 and my script was trying to set it but was on the wrong one until I updated it.

[Martin Iturbide]

Hi Andy

This are my first attemts to use with the unimix.exe tool. I have no idea how or what " truncate" is, or how to do it.
I only have those 3 IDS that are listed, if there is a way to "un-trucate" this, just to see if I did something strange, let me know.

I tried changing the volume on ID 1, 2 and 3 without any results. I didn't tried ID 0 yet, since it does not show on the unimix -names report.

Regards

[Dave Yeo]

Hi Martin, truncate just means cutting off the end, with end being any size. So a list of 10 items could be truncated down to the first 3 items, or your last name could be truncated to I

[Martin Iturbide]

Hi

Oh, I thought that "truncate" mean some kind of technique, in that case the unimix -names and -list reports are complete.
