Any progress on this? I'm asking it because 2.6.29 kernel will likely go out soon, and all patches should be merged before the merge-window is opened. If you have no time, either we skip it or I'll do a quick fix. thanks, Takashi

[alsa-devel] Correct macro for Headset widgets
by Lopez Cruz, Misael 18 Mar '09

18 Mar '09

What is the correct way to declare a Headset widget in a machine driver? I originally thought that by using SND_SOC_DAPM_HP macro was enough, but it's not since the headset is both headphones and microphone. In my machine driver I have the following widget and map for headset: SND_SOC_DAPM_HP("Headset Jack", NULL) ... /* Headset: HSMIC (with bias), HSOL, HSOR */ {"Headset Jack", NULL, "HSOL"}, {"Headset Jack", NULL, "HSOR"}, {"HSMIC", NULL, "Headset Mic Bias"}, {"Headset Mic Bias", NULL, "Headset Jack"}, but the "Headset Mic Bias" widget never gets powered when the "Headset Jack" pin is enabled. When the audio map is scanned, only valid routes are powered: DAC-Output, Input-DAC, Input-Output, DAC-ADC. And "Headset Jack" (declared as SND_SOC_DAPM_HP) is not a valid input endpoint, then the capture route becomes invalid. Can we have a macro specifically for Headset widgets? Thanks, -Misa

Instead it did make all play attempts (even non MMAP) to crash. (no crash details available since I desided to forget about it for now, working on unrelated issues for awhile) I did disable the MMAP so that player wont crash when requesting MMAP. System still dumps the bad pages at unload, play and capture seem to work OK, not tested extensively thou. -- Timo

[alsa-devel] Tenx USB audio adapter
by PETER EASTHOPE 17 Mar '09

Folk, I was advised to ask about the Tenx USB audio adapter here. lshal claims it is a standard HID device and a standard USB device. Ref. http://carnot.yi.org/lshal1.out Nevertheless, sound in and sound out both fail in my system. Some information is at the bottom of this page. "http://carnot.yi.org/DebianPage.html#USBAudio" Any suggestions? Thanks, ... Peter E. -- http://members.shaw.ca/peasthope/ http://carnot.yi.org/ = http://carnot.pathology.ubc.ca/
