No Playback on MacBook (loud click instead)

Help for Audacity 2.x on Mac OS X.

ImageThis forum is for Audacity 2.x on Mac OS X 10.4 and later.

Please state which version of OS X you are using, the exact three-section version of Audacity from Audacity > About Audacity and whether you obtained the .dmg installer or the zip.

Audacity 1.2.x and 1.3.x are obsolete and no longer supported. If you still have those versions, please upgrade here. The old forums for those versions are now closed, but you can still read the archives of the 1.2.x and 1.3.x forums.

Yes, it is still work.

After 10 minutes it still work. Also when I let laptop sleep, when resumed after two hours it still work. After reboot it still work. I have to shutdown and then power on to induce this issue (sorry if I somewhere wrote "reboot" previously, it has to be shutdown, about second wait and then power on).

"antipop" doesn't help (I made 10 minutes length tone, whole was played without any sound - except first beep and loud click). Nothing happened, although "antipopd" was launched.
When I try manually what "antipop" should do (i.e run "say" command with space every ten seconds), then after fifth say " " tone began audible (btw. it means that it would take about 50 seconds until Audacity start playing when "antipop" do what should do).

EDIT: I'm trying to find what was wrong, because "antipopd" is just a shell script with endless loop with say " "
EDIT2: Ah, AntiPop installer firstly starts "antipopd" as root. And launchctl wasn't quite successful when it should start under logged in user.

OK thanks for testing.

Can you confirm if you shut down the Mac, open Audio MIDI Setup, look at the output settings for built-in audio then start Audacity, do settings change in Audio MIDI Setup? If you generate a tone in Audacity and try to play it, do settings change then?

Can you confirm if you shut down the Mac, leave Audacity alone then play a file in Quick Time, does it click the first time you play it, and then play OK second time?

Are we talking about this?:

(Vestavěný mikrofon = Internal mic, Vestavěný vstup = Internal input, Vestavěný výstup = Internal output)

After fresh power on:
int. mic: 44.1kHz, 2ch/16b int, M = 0.083 (-10dB)
int. input: 44.1kHz, 2ch/16b int, HW freq converter disabled, 1: 0.5 (0dB), 2: 0.5 (0dB)
int. output: 44.1kHz, 2ch/16b int, 1: 0.254 (-28.5dB), 2: 0.254 (-28.5dB)

After Audacity is launched (but nothing else):
int. mic: 44.1kHz, 2ch/16b int, M = 0.083 (-10dB)
int. input: 44.1kHz, 2ch/16b int, HW freq converter disabled, 1: 0.5 (0dB), 2: 0.5 (0dB)
int. output: 44.1kHz, 2ch/16b int, 1: 0.254 (-28.5dB), 2: 0.254 (-28.5dB)

After tone generated and (unsuccessfuly) played in Audacity:
int. mic: 44.1kHz, 2ch/16b int, M = 0.083 (-10dB)
int. input: 44.1kHz, 2ch/16b int, HW freq converter disabled, 1: 0.5 (0dB), 2: 0.5 (0dB)
int. output: 44.1kHz, 2ch/16b int, 1: 0.254 (-28.5dB), 2: 0.254 (-28.5dB)

I.e. no change.

When I power on Mac, didn't touch anything except I play audio (through Quicklook in Finder), it plays immediately without any issues. First time, second time, doesn't matter.

When I power on Mac, launch Audacity (just launch, nothing else), try to play audio through Quicklook in Finder, it also plays without any issues. But when I try to play audio in Audacity (for example generated tone) an issue appears.

Thanks again for testing (yes I meant the Audio MIDI Setup utility).

So this isn't a problem with Audacity making visible settings changes to the audio device, and not a problem when it queries the audio device on launch. It just occurs when you play in Audacity.

I suppose you could rebuild current Audacity with http://code.google.com/p/audacity/source/detail?r=12231 and http://code.google.com/p/audacity/source/detail?r=12232 reverted to isolate if those commits were the cause. Do you build Audacity on Mac ( http://wiki.audacityteam.org/wiki/Building_On_Mac ) ?

Hmm, probably not :-(
I'm stuck at compiling wxWidgets 2.8.12 on OS X 10.9

Are you following http://wiki.audacityteam.org/wiki/Build ... _wxWidgets ?

You do need Xcode 5.0 or greater on Mavericks. I'll update the Wiki page presently to say that.

As you are building widgets from a script, all the preceding steps on http://wiki.audacityteam.org/wiki/Building_On_Mac must be followed.

If rebuilding with older PortAudio doesn't work for you I might try to do it, but the Audacity build system has certain quirks at the moment.

Moreless.
I already have cmake (version 2.8.12) and pkg-config (version 0.28). I believe that's enough.

wxWidgets: I missed that it really needs sdk 10.4u (i.e. Xcode 3.2.6)

Conclusion: No, I didn't exactly follow that page. Sorry about that.

(EDIT: Updated to make post more clear and correct)

I've updated the Wiki page http://wiki.audacityteam.org/wiki/Building_On_Mac .

The whole process on that page depends on linking Xcode 3.2.6 with later Xcode. This is OK when updating to Mavericks from earlier OS X as I did, because you can install Xcode 3.2.6 on Mountain Lion or earlier.

I really don't know if you can install 3.2.6 on Mavericks. The only search result I can find is that 3.2.6 installation crashes then the machine won't reboot properly until you reinstall Mavericks. :evil:

I'll see if I can find any more out about this.

I'm still trying to find out. Did you make any more progress?

If you reduce or increase Audio to buffer in the Audacity recording preferences, does it make any difference to the click problem?
