Re: alsa-driver-linuxant and the HSF driver

["Linuxant support (Jonathan)" <support@xxxxxxxxxxxx>]

Hi,

it is important to note that the solution (workaround) I gave to Alex is 
specific for his setup, he probably had a HDA sound device with a 
non-HDA modem which is not a common setup. With this specific setup, the 
command can be used if you experience crashes or audio problem, it might 
cure them without a negative impact on the HSF driver.

Users with a HDA sound and HDA Conexant modem setup, which is common in 
newer laptops, that have problems (a crash, sound related issues, 
etc...) should try with the latest stable version of 
alsa-driver-linuxant available at:

http://www.linuxant.com/alsa-driver/

At the moment, the latest experimental DEB build is available at:

http://www.linuxant.com/alsa-driver/alsa-driver-linuxant_1.0.19git20081204_all.deb 


If problems persist even with the latest version, please send to 
support@xxxxxxxxxxxx a "dumpdiag" generated with the 'sudo hsfconfig 
--dumpdiag' command under Ubuntu ('hsfconfig --dumpdiag' in a root shell 
for other distributions).
