I now had sound. I rebooted later in the day and the same thing happened. So I followed the steps again, and once again, I had sound. I just wanted to post this to let others know the solution.

A workaround for no sound in non-Apple applications
Feb 18, '05 10:02:00AM • Contributed by: MadProphet
I noticed after the 10.3.8 update that all of my Non-Apple apps (i.e. Entourage, Excel, PSI (Jabber Client), Flash) lost sound. I got the startup chime, I could use the Volume Keys, but no sound. Finally I got on webchat with Apple and they had me shut down all non-working applications, then open GarageBand, play something, then open the apps again.

A workaround for no sound in non-Apple applications
I don't know if this is related or not, but I found yesterday working with both QuickTime and VLC on my G5 that after switching to VLC, I loose sound in all my other applications. Turns out, VLC was switching the whole system over to using the optical sound out, which has nothing attached to it, and so after it did that I had to go into the Sound System Pref and switch it back to the built in speaker. Oh, VLC also had the option of picking which device it made sound with, but whenever I switched it over to built in as well, it crashed (first time a kernel panic even). I wonder if perhaps these issues are related?

Oh my God!!
VLC No Audio-FIXED (kinda)
None of these other suggestions worked for me, 10.4, 1GHz Tibook, VLC 0.8.1.
A workaround for no sound in non-Apple applications
Hello,
A workaround for no sound in non-Apple applications
I have had the same problem, and like the first comment in reply suggests, I would bet that the user has a mac with digital audio out ports (e.g. G5)--perhaps also with an iMic. I find that my output source selection sometimes does not 'stick', reverting to digital audio out as soon as I close the Sound Preference pane, after I have already selected an analog output source. This behaviour often occurs after using VLC. Selecting the third (analog) output source, closing the prefpane, reopening the prefpane and selecting the original (first) analog output source fixes the problem for me. It's annoying.
Try the hidden Apple-provided utility, Audio MIDI Setup Utility
I've had sound problems before which affected both Apple and non-Apple programs. To fix them, I opened up the Audio MIDI Setup Utility, which is an Apple-provided program in my main Utilities folder. It has all sorts of settings which might help people. It's like a more detailed version of the Sound control panel in System Preferences. My particular problem was loss of stereo sound, so I had to select 2ch-16bit from a drop-down (and equalize the volume of the two stereo channels).
A workaround for no sound in non-Apple applications
I think the problem is that after the update the default sampling rate is changed to 96k in Audio/Midi Setup. Switching that back to 44.1k fixed the problem for me.

Hello,
A workaround for no sound in non-Apple applications
I've also noticed that when trying to play various types of video I've had something go wonky with the sound, effectively "muting" my G5 completely though it reported sound as being output. It definitely has something to do with QT Player, VLC, and perhaps only specific types of sound in a movie, but I have yet to figure out exactly what combination of things causes the issue.
Wonky sound solutions
I had an issue where VLC would play ear-screeching speaker-killing sound, but only with certain movies. After quitting the app I'd lose sound till I played something in iTunes. Turns out that VLC on newer Macs (in my case a dual 2.5ghz G5) has an incompatibility with the AC3 audio format and the optical audio out (I believe), which I was using. If you download the latest beta of VLC, however, it fixes this issue! |
