After upgrading from sys-kernel/gentoo-sources-2.6.27-r10 to sys-kernel/gentoo-sources-2.6.30-r6, net-dialup/hsfmodem-7.80.02.04 is no longer able to build alsa modules for kernel. It also brokes sound as running hsfconfig renames existing alsa modules and doesn't build new. nnn # ls /lib/modules/2.6.30-gentoo-r6/kernel/sound/pci/hda/ snd-hda-codec-analog.ko snd-hda-codec.ko.REPLACEDBYhsfmodem snd-hda-codec-conexant.ko snd-hda-intel.ko.REPLACEDBYhsfmodem Reproducible: Always Steps to Reproduce: 1.Emerge, build and boot to sys-kernel/gentoo-sources-2.6.30-r6 2.Emerge net-dialup/hsfmodem-7.80.02.04 if it has not already been emerged 3.Run hsfconfig as root to try to build the kernel modules 4.Run ls /lib/modules/2.6.30-gentoo-r6/kernel/sound/pci/hda to see renamed modules. 5.Run ls /lib/modules/2.6.30-gentoo-r6/updates/ to see that there are no alsa modules where they should be. 4.Try to dial-up. 5.Try to play some sound. 6.Try to restart alsasound.

Sound is broken. Expected Results: The alsa kernel modules should have been successfully built. Modem should dial. Alsa should work too. My sound card is Intel HD Audio with Analog Device HD-audio codec, my modem is Conexant HSF so i marked them to be built as a modules during kernel configuration. Then i decided to switch off in-kernel alsa to try out separate alsa-driver package (1.0.20) with patch from linuxant with improved support for Conexant chipsets and the HSF driver as was advised on their website. All compiled ok. hsfconfig build all modules. Modem works. But the modem can't establish connection due "clicks" in its signal. I have a record of it. The same version of hsfmodem driver works ok with gentoo-sources-2.6.27 (with in-kernel alsa) without any patching. I also have applied alsa-patch from linuxant to gentoo-sources-2.6.30-r6 to try it with in-kernel alsa (1.0.20). This works too but also with "clicks". Also with patched alsa-modules (both in-kernel or separate package) running hsfconfig doesn't replace them. Driver just picks them up. I was able to record sound from modem. It is in the attachment and can be played with: aplay -t raw -f S16_LE -r16000 <filename> Note that it shows just clicks, i even did't try to establish connection (it's impossible due clicks) so i swithed from pulse to tone dialing as my provider supports only pulse dial-out.
Created attachment 203534 [details] Handshake sound of modem with "clicks" Can be played with aplay -t raw -f S16_LE -r16000 <filename>
Created attachment 203535 [details, diff] Patch for alsa-driver from linuxant website I've aplied this patch to both the external alsa-driver-1.0.20-r1 package which is not supported by Gentoo maintainers and to gentoo-sources-2.6.30-r6.

After some research i founded that the problem with "clicks" was in not properly configured alsa which was not able to determine right wake-up timing for controller by default. Clicks disappearied after manual setting "bdl_pos_adj" in alsa.conf I've added: options snd-hda-intel model=hp position_fix=2 bdl_pos_adj=32 to alsa.conf to make it work without clicks. But this works for me only after applying patch from linuxant to kernel sources. Without patch driver fails to load its modules with post install messages like (after hsfconfig): Warning: no device detected by hsf driver - HDA modems may require reboot Note: HDA support not compiled in the driver
