[alsa-devel] Analog Loopback controls disabled for IDT/STAC codecs
by Takashi Iwai 02 Mar '09

02 Mar '09

Hi, I disabled now "Analog Loopback" controls for IDT/STAC codecs on sound git tree as default since these are rather confusing for users, more harmful than useful. But the feature is still available. It can be enabled via sysfs "hints". For example, # echo "loopback = yes" > /sys/class/sound/hwC0D0/hints # echo 1 > /sys/class/sound/hwC0D0/reconfig will take the mixer elements back. Also, hp_detect and gpio-bits can be changed similarly on the fly. If you find any problems with this change, please let me know. thanks, Takashi

[alsa-devel] [PATCH] cs4270: add support for slave mode configurations

Added support for scenarios where the Cirrus CS4270 audio codec is slave to the bitclk and lrclk. Mixed setups are unsupported.

[alsa-devel] Support for fujitsu T421x
by John Kha 02 Mar '09

02 Mar '09

I have a Fujitsu Lifebook T4210 (very similar to the T4215) and wish to work on adding support for these models in patch_sigmatel.c. I have ran the alsa-info script, once after a fresh boot, and once after changing the model a few times: Virgin: http://www.alsa-project.org/db/?f=e76430dbf61b0e2c1ff199c9d1c85051a0341508 With Model Changed: http://www.alsa-project.org/db/?f=cdd45e343c143052e18f9706e65eef8865696606 After trying various models, I have been unable to get the audio to output to the correct pin groups. I have managed to use hda_analyzer.py to change some of my hardware settings, and have an idea of what verbs i need to send. What I need is some information on the architecture of the driver, or an idea of where to edit things. I would just say the config here and ask someone else to edit patch_sigmatel.c, but this is only the first of the issues I want to fix, so some knowledge of how to edit myself would be useful. -- John C.

[alsa-devel] arecord channel limitation

hi all, is there any reason, why arecord limits the channel count to 32? best, tim -- tim(a)klingt.org http://tim.klingt.org Desperation is the raw material of drastic change. Only those who can leave behind everything they have ever believed in can hope to escape. William S. Burroughs

[alsa-devel] Status of the alsa sbxfi driver
by Brandon Ehle 02 Mar '09

02 Mar '09

I merged the topic/sbxfi branch from git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable-2.6.git into my latest 2.6.29-rc6 build. I've done a few quick tests and I have not run into any issues so far (except the driver has an excessive amount of kprintfs). Is this the latest version of the sbxfi driver? _From following the alsa-devel list and the git tree above, there doesn't seem to be any changes since Oct 30 or so. What work needs to be done to get this driver into a state where it could be pushed to the main alsa git and eventually to Linus' tree?
