[hsflinux] Fedora 7 volume control issues...

Some months back I reported that I was having problems with my audio 
sound control after installing the hsfmodem driver on my HP 2315nr 
laptop. To recap here's what's going on. Under Fedora 7 with the
ALSA incarnation, my volume controls work properly. That is there is
master control handled both the headphones and the laptop speakers.
the headphones are not plugged in the volume controller adjusts the 
speaker volume. When the headphones are plugged in the speakers are 
muted and the volume controls the headphone volume. This was a step 
forward from Fedora 6 where the Alsa control had a slider for each
it was necessary to mute the speakers so that sound did not play out
the speakers and the headset at the same time.

I was quite happy to see that linuxant offered a driver to allow the 
modem to work with Linux. I purchased the license and installed the 
driver, but the included Alsa with the modem driver doesn't seem to
quite right. With both Fedora 6 or 7 the Alsa included with the
provides one volume control which does indeed control the system
but does not seem to know that the headphones are plugged in and mute

the speakers. A user sent me a patch that I had some luck with under
6 which added the second control back to the mixer panel for the 
headphones, but I haven't been able to get that solution to work in
current configuration.

In the coming weeks I'll need to use the modem much more for work. I
hoping to resolve this issue as I do use the headphones quite a bit
play music as well. To date I've been reduced to installing the
driver when I know I have modem needs, but removing it when I'm not 
using the modem so that the speakers/headphones behave properly. 
Clearly, this is a bad solution, but my efforts to solve this on my 
own(I've burned up google!) have been useless.

Any ideas would be appreciated.
