Those USB sound cards are almost always mono in the actual hardware, and that's what you'd normally want TTD set to. Not getting any audio when set to mono in TTD is unusual. And if you set it to stereo when it's actually a mono sound card I'd actually expect the opposite problem...audio being too fast as half the samples (for the opposite channel) get thrown out when in stereo.Hello, everyone.
Unfortunately, the home server I was running TTD on crashed a several weeks ago and I've been trying to resurrect TTD on a new one. I'm having a problem that I didn't run into the first time, and I'm just looking to see if somebody can point me in the right direction. TTD recognizes the tones accurately and activates, but the recording sounds slow/warped (it's half speed - if I play it back at double-time with Audacity it becomes intelligible) and the file is twice as long as the test audio length. It's like something in the recording process stretched the audio out. After reviewing some previous posts here, I suspect it's an issue with the sampling rate, but no matter what adjustments I make, I can't fix the issue.
I tried changing the TTD setting for MP3 bitrate, left/right/mono audio, various settings for the USB audio adapter. Nothing seems to do the trick. While troubleshooting, I was able to determine that the original WAV being recorded also sounds the same way, before it's converted into MP3, so the problem isn't in the conversation process. I also tried recording the scanner audio using a different application (Audacity) and that works OK. I also noticed that my original TTD server Windows 7) was set to mono in the config file, but if I select that on the new machine (Windows 10) I get no audio. If I choose either Left or Right, I get the scanner audio. It's the same USB sound adapter. I did also grab another USB sound adapter I had laying around (different model) and experienced the same problem with that one, too.
Hopefully something I've missed will pop out for somebody. I'm really scratching my head over here. Thanks!
I've seen a very few reports of this in the past. I'm not sure we ever conclusively determined root cause. In at least two cases, reinstalling TTD seemed to solve it for the people having the issue, but never determined why that helped.
