[alsa-devel] [PATCH] usb: add USB_QUIRK_RESET_RESUME for M-Audio 49
by Jonathan Nieder 26 Nov '12

26 Nov '12

Some USB MIDI keyboards fail to operate after a USB autosuspend. The device is recognized by ALSA, but no events are received and the device goes quiet. $ amidi -l Dir Device Name IO hw:1,0,0 Oxygen 49 MIDI 1 $ amidi -p hw:1,0,0 -d <... play some notes ...> ^C 0 bytes read A workaround is to disable USB autosuspend for these devices by putting AUTOSUSPEND_USBID_BLACKLIST="0763:2027" (resp. 0763:019b) in /etc/laptop-mode/conf.d/usb-autosuspend.conf. In the spirit of commit 166cb70e97bd ("usb: add USB_QUIRK_RESET_RESUME for M-Audio 88es"), reset the device on resume so this workaround is not needed any more. Noticed on a kernel close to 3.2.10. Tested against 3.6.5. Debian's 2.6.32.54-based kernel did not seem to be affected, though it's not clear whether that is due to code or configuration.

[alsa-devel] [PATCH 0/3] ASoC: Davinci: McASP: add support new McASP IP Variant
by Hebbar, Gururaja 26 Nov '12

26 Nov '12

The OMAP2+ variant of McASP is different from Davinci variant w.r.to some register offset and missing generic SRAM APIs support Changes - Add new MCASP_VERSION_3 to identify new variant. New DT compatible "ti,omap2-mcasp-audio" to identify version 3 controller. - The register offsets are handled depending on the version. - Provide a config option to indicate missing SRAM API support. While here, fix a typo caused by recent commit (cf53756 - ASoC: davinci: davinci-pcm does not need to be a plaform_driver) Note: DMA parameters (dma fifo offset) are not updated and will be done later.

In other words, this should be a hard error.

However it will at least be complete on Davinci platform.

[alsa-devel] [2.6.32.y] Re: [regression] no sound from Fujitsu Pi laptop unless headphones plugged in
by Jonathan Nieder 25 Nov '12

Hi Willy, Please consider cfc9b06f0bef ALSA: hda - Add a pin-fix for FSC Amilo Pi1505 for application to the 2.6.32.y tree. Without this patch, the Amilo Pi 1505's internal speaker is silent unless a jack is plugged into its headphone jack. Jose Manuel Castroagudin noticed[1] that 2.6.30 is not affected, so this seems to be a regression. The patch was applied upstream during the 2.6.33 merge window, where it worked. That said, I didn't manage to track down anyone with a Pi1505 to test it against 2.6.32, so thoughts from alsa folks on whether this is appropriate for 2.6.32.y would be useful. Hope that helps, Jonathan [1] http://bugs.debian.org/599582 has many more details.
