[alsa-devel] [PATCH] ASoC: atmel-pcm-pdc: merge atmel-pcm back in
by Alexandre Belloni 01 Apr '15

01 Apr '15

atmel-pcm.c was split into two files to create a generic framework for both PDC and DMA. atmel-pcm-dma.c is using the generic dmaengine framework since 95e0e07e710e (ASoC: atmel-pcm: use generic dmaengine framework). Merge atmel-pcm.c in atmel-pcm-pdc.c as this is now the only user.

[alsa-devel] [PATCH] ASoC: rsnd: add Synchronous SRC mode

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Renesas R-Car sound SRC (= Sampling Rate Converter) has Asynchronous/Synchronous SRC mode. Asynchronous mode is already supported via DPCM. This patch adds Synchronous mode on it.

[alsa-devel] [PATCH 0/5] Intel SST driver restructure
by Jie Yang 01 Apr '15

01 Apr '15

In order to prepare for the upstreaming of Skylake drivers and to allow reuse of code between different Intel audio DSP products, this patch series restructures the Intel directory as follows: 1. Create "common" directory. Move common files into this directory. 2. Create "boards" directory. Move all machine drivers into this directory. 3. Create "haswell" directory. Move all remaining hsw/bdw code into this directory. 4. Create "baytrail" directory. Move remaining baytrail driver to this directory. 5. Create "atom" directory. Move all MCG platform drivers(including sst/ folder) to this directory. Todo next step: 1. Change and move atom related codes(in atom/sst/) to corresponding and try share as many as possible codes(e.g. sst_acpi.c). 2. Share more common codes about IPC for different platforms, e.g. The methods for queueing and sending/reciving Tx/Rx messages, The methods for mailbox IO, The IPC error return codes, etc. Jie Yang (5):

[alsa-devel] Rane SL2/3/4 driver?
by Be 01 Apr '15

01 Apr '15

Hi, I recently published the first version of Crossfade GNU/Linux, a distro for DJing from USB drives on any PC (see http://mixxx.org/forums/viewtopic.php?f=1&t=7031 for details). I just tried it on my friend's Macbook which he uses with a Rane SL4 USB sound card. I realized there is no Linux driver for the current line of sound cards sold for digital vinyl emulation with Serato DJ. These are the Rane SL2, SL3, and SL4 (http://serato.com/hardware/all/mixers-interfaces ; the Denon DS1 was also recently announced but not available yet: http://serato.com/latest/blog/17973/announcing-denon-ds1 ). They range from 4 in/4 out to 10 in/10 out and all have phono preamps built in. There appears to be support for the old and discontinued Rane SL1, which used USB 1.1, but the SL2/3/4 use USB 2.0. Has anyone thought about writing a driver for these?
