A headphone audio fix for the Logitech USB Headset 350 Apps
I read good reviews about the Logitech USB Headset 350, so I was dissapointed to have difficulty in getting its headphones to work consistently. The mic would work and the system reported no errors, but the headphones would get no sound.

Opening Audio Midi Setup and toggling from '2ch-16bit' to '1ch-16bit' (pausing to adjust the volume to cause it to make noise, just because) and then back to '2ch-16bit' seems to make it work consistently. For what it's worth, as far as sound quality goes, I agree with the reviewers in giving them a reasonable thumbs-up.

I didn't experience the sound problems that came about with the 10.3.8 update, but I know it had equally obscure fixes (eg. launch GarageBand and make noise). Can anyone provide insight as to why things aren't so much "it just works" with the audio?

No idea why, but I have a similar problem with my Logitech Stereo USB 200 headset. I have to go into system prefs > sound and mute then unmute them to make them work when I want to use them - its the microphone that's more problematic than the headphones for me.

I've heard other people have the same problem and fix, and I also know that mine work fine on Windows XP - so it's not a hardware problem per se.

A headphone audio fix for the Logitech USB Headset 350

I googled USB 350 Logitech and got:

http://lists.freebsd.org/pipermail/freebsd-multimedia/2005-April/002039.html

with some the text copied below:

3. Is your USB controller ohci or uhci?
uhci has no problem. But ohci has the full duplex problem.
microphone and speaker can't be use simultaneously without full duplex.
Then a USB headset can't be use with ohci.

But if you want to use it as headphone only, or microphone only,
ohci has no problem.

3'.If you want to use microphone and speaker simultaneously with uhci,
you must comment-out below lines
at function uaudio_init_params() in uaudio.c

if ((sc->sc_playchan.pipe != NULL) || (sc->sc_recchan.pipe != NULL))
return (-1);


Now I'm trying to figure out how to implement something 10.4.3.

I got sick of having to go to System Preferences and then to Sound and then check/uncheck mute to get my Logitech 350 USB headset to work, so I made an Applescript to automate this, from clues I found elsewhere on the intraweb.

tell application "System Preferences"
	set current pane to pane "com.apple.preference.sound"
end tell
tell application "System Events"
	tell process "System Preferences"
		click checkbox "Mute" of first group of window "Sound"
	end tell
end tell
tell application "System Events"
	tell process "System Preferences"
		click checkbox "Mute" of first group of window "Sound"
	end tell
end tell
I'm new to Applescript and have no idea what I'm doing, but this works for me (as long as the Logitech 350 is set to the main output source, I believe). I am also using SoundSource from Rogue Amoeba to quickly shift to the headphones from the default system sound. Additionally, I have set this to a trigger in Quicksilver (Shift-Cmd-M), so I can do it good and quick when I am answering a Skype call! Works well... but hopefully Logitech/Apple will come out with a fix for this, as it only seems to have started affecting me since I upgraded to 10.4.3.

A user on Apple's Support Discussion forums adds slightly different suggestion: Enable the 'thru' checkbox under Audio Input when editing the properties for 'Logitech USB Headset' using the aforementioned /Applications/Utilitiies/Audio MIDI Setup.app

BTW, I'm using a Logitech USB Headset 250, which apparently has the same minor issue as the 350. Otherwise, it seems to be a pretty good product.

Well, it seems that the aforementioned fix (i.e. using 10.4's Audio MIDI Setup.app) doesn't *entirely* work. That is, something seems to randomly un-set the 'thru' selection, thereby muting the headset audio at times. Until someone suggests a better solution, here's a hack that seems to work: once you have a proper, working setting with the Audio MIDI setup, prevent it from being changed by locking (write-protecting) the the preference file. (As a warning, doing this may interfere with some other aspect of OSX's audio subsystem if you use the Audio MIDI Setup.app for other things):

1) Get your headset audio working, as previously described.
2) In your local Prefs folder, (~/Library/Preferences/) locate the com.apple.audio.AudioMIDISetup.plist file and LOCK it using the Finder's Get Info dialog.

I'm really unsatisfied with this solution, but for the time being, it seems to do the trick.

BTW, in a somewhat related note: I've found Rogue Amoeba's freeware app SoundSource to be quite useful when switching OSX's audio back and forth between the headset and internal speakers. Beats going to System Preferences -> Sound each time you want to switch.

Hey
little thing with my USB headphones 350 from Logitech, since its annoying with old sound cards like my creative soundblaster live, it will have music and stuff from my speakers which is connected to my sound card. But when it comes to windows prompts and games its on the headphones, is it possible to have them running simaltaniously or is it with the whole onbourd motherboard connections and stuff?

HELP DAMNIT
