[alsa-devel] [PATCH v2 0/3] Atmel ALSA drivers
by Hans-Christian Egtvedt 05 Feb '09

05 Feb '09

This patch series is the second revision after the initial review on alsa-devel mailing list. I have addressed the feedback and fixed up the drivers appropriatly, at least I hope so. I've settled to put the drivers in the more common sound/atmel and added an "Atmel devices (AVR32 and AT91)" menu entry in the ALSA part of kconfig. No drivers are available for AT91 yet, but the AC97C driver should be quite simple to add support for AT91 devices as well. The patches are formatted against v2.6.29-rc3 tag from Linux repository. In addition a vital DMA patch[1] is needed, which adds a cyclic DMA interface to the DesignWare DMA controller. 1: http://avr32linux.org/archives/kernel/2009-February/002088.html http://avr32linux.org/archives/kernel/2009-February/002087.html -- Best regards, Hans-Christian Egtvedt

Impact: cleanup snd_pcm_new takes a char *id argument, although it is not modifying the string. it can therefore be declared as const char *id.

by Fernando Moro 05 Feb '09

05 Feb '09

I would be very gratefull if someone could write an alsa driver for the Lexicon lambda soundcard. I think there are a lot of people with the same problem, but I don't have the necessary knowledge. I can provide the drivers for windows. I hope you can help me, and I hope your news about this device. Thank you.

hi everybody, this is my first post in the list. currently i work in a new project, and i need is some help to finish this. I wrote an application whose take data from serial port or from bluetooth device(spp) and store the data in a raw file(the data is audio). Now i need to do this: the data received from the port, send to internet through voip software like ekiga, kphone, etc. I read writing-an-alsa-driver.pdf, alsa-driver-api.pdf but i dont know how create a source of data, for softwares of voip take data like a microphone and also receive data from these programs. I've been looking serial-u16550.c would be something similar to what the bluez bluetooth headphones Sorry for my english is not very good. greetings

[alsa-devel] Onkyo SE-200PCI : What can the first pair of RCA output do?
by tycordinal 05 Feb '09

05 Feb '09

Hi, I am running on Fedora 9 / Alsa 1.0.18a. I have tried to play 24bits 6ch PCM file on Onkyo SE-200PCI and the 6ch output from VGA-like connector are very good. Thanks for the good work! I would like to know what is the intention for the first pair of RCA output? Apparently, I am able to get the first two channels out of the 6 channels audio file when I play through plug:surround51, but the remaining four channels were not able to get heard. Could alsamixer or any asound.rc options can make Onkyo SE-200PCI to produce a downmix of 6ch on the first pair of RCA output? Can this be done through the hardware chips themselves, or any asound.rc options can make this work? Or could it be, the first pair of RCA output is really hardwired, like ice1712/se.c has suggested because of WM8740 chip, to always give an exact copy of the first 2 channels out of the 6 channels playback? Thanks.
