There have been several reports of failures under 2.6.28 kernels, of modems dependent on snd-hda-intel code, that served well under earlier kernels. One possibility is that the modem code requires updating. Another (perhaps overlapping reason) is that merely the ALSA code needs updating. On a MAC laptop alternately booting MAC or Linux, the the ALSA installed with Ubuntu Jaunty was 1.0.18 and sound was not functional Following some online guidance, I did an upgrade to the current stable ALSA release 1.0.21: ------------------ $ cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.21. Compiled on Sep 26 2009 for kernel 2.6.28-15-generic (SMP). -------------------- which did bring in sound support as promised. So perhaps some of you having modem problems should also do this ALSA upgrade, to assess if it solves the modem problem. We have thus had successes in the past, with snd-hda-intel dependent modems. For those using Ubuntu and having an alternate ethernet connection, there is a short script that does it all. Read http://webupd8.blogspot.com/2009/09/alsa-1021-upgrade-script-for-ubuntu.html and get the script AlsaUpgrade-1.0.x-rev-1.17.tar from the bottom of http://webupd8.blogspot.com/2009/08/alsa-upgrade-script-for-debian-ubuntu.html With the following minor edits below, the script did ALL without any problem. MarvS ============= In the second section, edit to: PACKAGE=1.0.21 alsa1021 () { DRIVER=alsa-driver-1.0.21 FIRMWARE=alsa-firmware-1.0.20 LIB=alsa-lib-1.0.21a PLUGINS=alsa-plugins-1.0.21 UTILS=alsa-utils-1.0.21 TOOLS=alsa-tools-1.0.21 OSS=alsa-oss-1.0.17 } and a couple of paragraphs further down, changing alsa1020 to alsa1021 per final below: package () { echo -n "Choose Alsa Package (1) $PACKAGE default[1]: " read PACK case $PACK in "" ) alsa1021 ;; [1] ) alsa1021 ;; * ) alsa1021 ;; esac ALSASRCDIR=${SRCDIR}/Alsa-${PACKAGE} }
