Hello Lajos, MarvS and all others interested, I did some debugging of the ALSA driver while trying to get the modem working with alsa > 1.0.12. Mine is a SI3054 on an Fujitsu Siemens Lifebook S7020. Here are the results! Jan 16 20:03:46 YYYY kernel: ALSA XXX/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:555: hda_intel: azx_get_response timeout, switching to polling mode...

It should be (according to documentation) something between 0x1 and 0xf. Seems to be a bug somewhere! Still looking for the details! Joern
