Mic/Line in with UniAud (3.0.1)

(1/2) > >>

Jan-Erik Lärka:
Hi,

The new build(s) of UniAud show more and more of the built in sound card (ATI HDA, ALC888) functionality with unimix.
I'd like to use the now enabled/recognized Mic in and/or Line in, but "Digital Audio" recorder and the os2tk45 "Audio Recorder Sample" and "Direct Audio" samples either stall the computer or the application. VoiceType therefore can't enable input.

Are there something to do?

Regards,
//Jan-Erik

To be honest - I don't know if the inputs work on any versions of Uniaud - it would be good to hear from anyone if they used to work.

It may also be that Uniaud needs to be 'taught' how to connect the MMPM inputs to the appropriate ALSA/Uniaud inputs...

I'll try do some research on this topic.

Edit: a couple of old bug reports.... https://trac.netlabs.org/uniaud/ticket/224 and https://trac.netlabs.org/uniaud/ticket/97 indicate these problems have been around for a while

Edit2: uniaud readme talks about using the /m switch to enable mic input - are you using this?

--- Code: ---DEVICE=x:\MMOS2\UNIAUD16.SYS /V /C /M /L
  - /V - Verbose
  - /C - Enable CD output
  - /M - Enable Microphone output
  - /L - Enable Line-In output
Default: /C ((verbose messages; CD output enabled)
--- End code ---

Cheers,

There's also aswitch.exe along with aswitchsetup.cmd, I believe on recent ArcaOS installs,

--- Code: ---W:\MMOS2>aswitchsetup.cmd

 ASwitch makes your USB ports act like a headphone jack.
 It switches audio output from your built-in sound system
 to your USB headphones or speakers whenever you plug them
 in, and restores the default as soon as you unplug them.

 Would you like to install ASwitch? [y/n] n

--- End code ---

Untested here, actually I thought it also enabled USB microphone
Sometime back I had a USB turntable that presented itself as an USB microphone which did work without any setup

Thinking out loud - I assume the Thinkpad T470s has a built-in mic - I guess I could try test with that....

Yes, I think so too.

I have tried both /M (Microphone) and /L (Line input) but neither seem to make any difference on either of my machines.
VoiceType and the built in sound editor can't reach anything.
Even tried to reinstall Soundblaster Live 7.1 Card on the AMD desktop, with the only difference that it was unable use the built in card (even with parameter set in config.sys) and sb output could only handle one specific bit-rate audio output. No input there either.
One of your builds of uniaud32 enabled a bunch of controls in pmunimix, with line in/mic, but ...
