[PATCH] ALSA: HDA: Conexant auto: Handle multiple connections to ADC node
by David Henningsson 15 Feb '11

15 Feb '11

Conexant 20641 has several inputs to its ADC node, with one selector and individual amps for all inputs. This patch adds support in the Conexant auto parser to handle that case. It also means that the pin node's volume is being renamed to "Boost" to avoid name clash with the new volume controls on the ADC node.

[alsa-devel] plughw, access modes
by Nenad Sljivic 15 Feb '11

15 Feb '11

Greetings guys, I am dealing with the device driver for the chip that has his own hardware buffer and the DMA is not available. Therefore, driver doesn't support MMAP access and the data is copied using the copy file operation. My HW natively supports BE format. However, I would like to be able to play little endian pcm as well. The problem, occurs when I try to use plughw device in order to play LE pcm file " aplay: set_params:1022: Unable to install hw params: " My debugging session proved me that plughw device is trying to access device driver with MMAP_INTERLEAVED mode. Does it mean that this is the only way for plughw to access device driver, and that I am not able to use plugins unless do some heavy modifications of device drivers (implement mmap access). Am I missing something? Any info on this would be most welcome. Thanks, Nenad

[alsa-devel] [PATCH] New quirk for USB DAC 08bb:2704
by Omari Stephens 14 Feb '11

14 Feb '11

Howdy, all I have one of these: http://www.chordelectronics.co.uk/products_detail.asp?id=63 It's got one of these USB DACs inside ID 08bb:2704 Texas Instruments Japan The DAC has a single mixer control, Master, which allows you to adjust volume and mute/unmute. The fun thing is that the volume adjustment has no effect whatsoever. On machines running pulse, this means that output will be at 0dB pretty much all the time. (Of course, this is true of non-pulse machines also). The attached patch disables the Master control, which causes pulse to control levels entirely in software, as it should for this device. The main downside to this patch is that, while the volume part of the Master control is non-functional, the mute/unmute aspect does work as expected. I couldn't figure out how to change the Master control to just a mute/unmute control, but if someone has suggestions on what to do, that'd be appreciated. Judging by the comments in the code (and contrary to what I wrote in the map comment), I presume the mute/unmute control is the only reason why 08bb:2702 isn't doing this same thing. Cheers, --xsdg

[alsa-devel] Patches for new audio devices from Native Instruments
by Daniel Mack 14 Feb '11

14 Feb '11

Hi, Native Instruments announced a new set of audio hardware recently, and I have some patches ready to support them. See here for the details on their website: http://www.native-instruments.com/en/products/dj/traktor/ As I'm currently travelling and the only elaborated piece of hardware I got left is my mobile phone, I have to send them along as attachments. Many thanks to Mark Hills who rebased the patches for me so they should apply without trouble. In case of any doubts or questions - I'm reading my mails occasionally :-) Best regards, Daniel

This is a patch series to add the OMAP Digital Microphone driver for OMAP4. It includes the driver, a generic DMIC codec, platform devices, as well as HWMOD entries for OMAP44xx chipsets. Note: The DMIC codec driver was removed from this series as it was accepted for and merged for the 2.6.38 kernel.
