Windows Home 64-bit version 2004 build 19041. I downloaded the latest Tascam drivers, uninstalled the old ones, and installed the newest ones. I uninstalled and reinstalled the Tascam drivers. I uninstalled Audacity and deleted the Audacity folder in %appdata%. I checked the quality settings, and the default sample rate is set to 44100 Hz, 24-bit, as is the Tascam. In Audacity record settings, I have “Play other tracks while recording (overdub)” and “Record on a new track” checked, but all other options are off. The results may differ depending on each computer's configuration.
And, as I said, I can record as long as there is not another track already open in Audacity. The verification results of our TASCAM products with Microsoft's 'Windows 11 Version 21H2' are as shown in the table below. I can also play a track no problem through either my speakers, which are attached to an audio amp attached to the Tascam, or on headphones plugged into the Tascam. But if I have a track already open and press record to record an overdub track, the transport doesn’t start.
I can record a track from scratch just fine using a mic plugged into the Tascam. I have been using Audacity with my Tascam US-1200 for years, but it suddenly won’t work when I try to record an overdub.
