I'm trying to work out what could be different from my setup to yours. I have tried different PCs, different Linux distributions and two different HDSP cards. I'm using a HDSPe MADI Rev1.1 loaded with the latest firmware. Is yours the same ? May I send you a particular application to attempt running on your system with 1.0.27 and see if it works ? *Note* I can use all parts of 1.0.27 (eg, lib, alsamixer, aplay) /except/ for the Hammerfall driver (remains at 1.0.15) and it still works for me. I cannot install the new driver under an older kernel due to incompatibilities, but trying 1.0.18 or 1.0.27 (including later driver) with a newer kernel fails. I thought if I could somehow get the 1.0.15 hammerfall driver working with a new kernel (help ??) I could then somehow step through the subsequent changes made to the driver one by one till it breaks. This approach could take some considerable time, so any pointers as to how to do this would be much appreciated ! I do not profess to know much about alsa driver development, or how to even access the (svn ?) revision steps, but this might be the only way to work out what is happening here. Cheers, Bruce PS: I will also ask the Hammerfall Linux forum, but that seems a bit inactive now. > > > Flo -- Cheers, Bruce
