You're welcome. Please always remember to put the mailing list (linux-minidisc@lists.fu-berlin.de)
in CC when replying. This way all people on the list will be able to help, I'm not the only developer
and I also don't know all the code. That's why I bounced your mail to the list.

Just to avoid any misconception, you know that you need to hook up your MiniDisc Walkman to your computer
using an additional analog audio cable, don't you? I'm just saying that because many people incorrectly assumed
that all NetMD devices allow uploads, that is transfers from the device to the PC, over USB which is not correct.

Due to the limitations of the hardware, only the latest Sony model, the MZ-RH1 (and it's rebadged model MZ-RH200)
allows direct digital uploads over USB of standard MiniDisc (NetMD), all other NetMD devices and HiMD devices
in NetMD mode allow downloads, that is transfers to the device, only. So you either need to get hold of an MZ-RH1
or upload the tracks over analog cable. This limitation does not apply for HiMD devices operated in HiMD mode.

As Vincent already pointed out, Sox will not start recording unless a certain input level is detected at the soundcard
inputs. This explains why the recording didn't start.
