I just bought a TASCAM US-122L Audio Interface and I'm having huge problems with it. I'm confused, because some apps work, some don't. Computer Apple MacBook Early 2008 2.4 GHz Intel Core 2 Duo, Memory: 4GB 667 MHz DDR2 SDRAM, Mac OS X Version 10.5.6. TASCAM US-122L Firmware 1.12. TASCAM US-122L Driver 1.12. Here's a list of my findings so far: 1. QuickTime Player Pro Recording: will not record a new Audio Recording. As soon as I select it when TASCAM US-122L is the audio input device, QuickTime reports the following error: OSStatus error 2003329396 QuickTime Player Version 7.6 (472), QuickTime Version 7.6.0 (1290) 2. Wiretap Studio will not record when TASCAM US-122L is the audio input device. 3. iMovie does not record voiceovers when TASCAM US-122L is the audio input device. 4. Garageband has no problems recording when TASCAM US-122L is the audio input device. 5. Adobe Flash Player crashes and brings down both Safari and Firefox when I try to switch audio sources in Ustream.tv Broadcast console. 6. iTunes will not play any tracks when TASCAM US-122L is the audio output device. 7. Cubase LE included with TASCAM US-122L will record and play audio when US-122L is both the input and output device. 8. I can patch US-122L to Soundflower 2ch via LineIn (Rouge Amoeba) and feed Soundflower into Adobe Flash Player for Ustream.tv. I wonder if these problems are related to the TASCAM US-122L interface, specific apps or the operating system itself? I had no such problems with Behringer FCA-202 FireWire interface, but I needed an audio interface with mic preamps. I'll try Lexicon Alpha later this week and see if I run into the same problems.
