Therefore such kind of device expects the engine to perform 'clock recovery' by analyzing a series of isochronous packets from the device for the number of PCM frames on isochronous packet to the device. The mismatch between the 'ideal' throughput of the engine and the actual frequency of internal clock is the reason of clicks and pops, in my understanding. Furthermore, the number is variable at time e.g. Some of them expects to receive the number of PCM frames adjusted its internal sampling clock e.g. On the other hand, actual devices in market doesn't have the feature (sign.). This implementation relies on a feature called as 'clock recovery' in device side, which is a part of IEC 61883-1/6. IEC 61883-1/6 packet streaming engine in ALSA firewire stack transfers a series of isochronous packets which includes PCM frames exactly as the same as configured sampling rate e.g. This is a kind of issue dependent of each kind of devices. I've acknowledged this issue for a long ago. I was wondering if there was any helpful output / logs I could provide to help track this issue? This was using kernel 4.19 and 5.4 with and without snd-firewire-improve from. However, it's been a pain to get it to use in Windows 7 with any program outside of PT, so I'm considering selling it and buying something a little more Win7 friendly if I can't get it to work this weekend.Unfortunately it generates a little pop/click every 5 to 7 seconds in the recording and output. My friends and I were really impressed with the 003, especially when compared to the old m-audio FireWire 410 and Alesis Multimix 8 FireWire we'd used before. I'm using a TI-chip PCI firewire card and recorded some stuff a week ago with no hiccups. I uninstalled and reinstalled PT8 and the standalone drivers, but my computer will not recognize the 003 in my non PT8 DAWs and BSODs any time I launch PT. My computer immediately started getting the BSOD. The first update I downloaded overwrote the audio drivers I'd downloaded to get the 003 working. I had an opportunity to recently buy an iLok so that I could start updating PT8LE. I installed the stand alone drivers and finally got it to work with Windows 7. The audio drivers that are installed with it will not allow the other DAW software I use to recognize the 003. When I bought it, the guy included a copy of PT8LE that I installed but never used.
