[alsa-devel] Audinst HUD-mx2 covertly muting itself
by Tobias Klausmann 01 Nov '13

Hey, I have an Audinst HUD-mx2 external USB audio device: Bus 007 Device 006: ID 040d:340f VIA Technologies, Inc. $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: HUDmx2 [Audinst HUD-mx2], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: HUDmx2 [Audinst HUD-mx2], device 1: USB Audio [USB Audio #1] Subdevices: 1/1 Subdevice #0: subdevice #0 While the device works right in principle, every time an app closes the device, it mutes itself (or crash, this may be a Hw problem). There is no indication of the broken state in the mixer displays of alsamixer or alsamixer-gui, and amixer output does not indicate any change, either (see below).

[alsa-devel] [PATCH 0/8] Add and implement gen_pool_dma_alloc()
by Nicolin Chen 01 Nov '13

01 Nov '13

Previously, we don't have a specific gen_pool_alloc() for DMA usage; Instead, we need to use gen_pool_virt_to_phys() to convert the addr returned from gen_pool_alloc(). So each implementation of this has duplicated code. Thus add new helper function -- gen_pool_dma_alloc(). After gen_pool_dma_alloc() is introduced, we can replace the original combination of gen_pool_alloc()+gen_pool_virt_to_phys() with this new helper function. Thus this patch implement the helper function to all the current drivers which use gen_pool_virt_to_phys(). !!-------------------important------------------!! The later 7 patches need all related driver owner to test. We can here define a simple rule: 1, If one driver owner or maintainer doesn't like the mofication to his/her driver, just let me know. I would drop that patch. 2, If there's a bug and issue found after patch-testing, please reply the mail so that I can fix and refine the patch. 3, If one driver owner or maintainer is too busy and doesn't have bandwidth to test the patch, I would drop that patch from this series. We can reimplement it till there's someone test it. !!-------------------current progress-----------!! lib/genalloc: [Okay] ARM: davinci: [Untested] dma: mmp_tdma: [Untested] [media] coda: [Untested] uio: uio_pruss: [Untested] ALSA: memalloc: [Tested] by Nicolin Chen with i.MX6Q SabreSD ASoC: davinci: [Untested] ASoC: pxa: use [Untested] Nicolin Chen (8): lib/genalloc: add a helper function for DMA buffer allocation ARM: davinci: use gen_pool_dma_alloc() to sram.c dma: mmp_tdma: use gen_pool_dma_alloc() to allocate descriptor [media] coda: use gen_pool_dma_alloc() to allocate iram buffer uio: uio_pruss: use gen_pool_dma_alloc() to allocate sram memory ALSA: memalloc: use gen_pool_dma_alloc() to allocate iram buffer ASoC: davinci: use gen_pool_dma_alloc() in davinci-pcm.c ASoC: pxa: use gen_pool_dma_alloc() to allocate dma buffer arch/arm/mach-davinci/sram.c | 9 +-------- drivers/dma/mmp_tdma.c | 7 +------ drivers/media/platform/coda.c | 5 ++--- drivers/uio/uio_pruss.c | 6 ++---- include/linux/genalloc.h | 2 ++ lib/genalloc.c | 28 ++++++++++++++++++++++++++++ sound/core/memalloc.c | 6 +----- sound/soc/davinci/davinci-pcm.c | 3 +-- sound/soc/pxa/mmp-pcm.c | 3 +-- 9 files changed, 39 insertions(+), 30 deletions(-) -- 1.8.4

[alsa-devel] [PATCH v2] ALSA: hda - not choose assigned converters for unused pins of Valleyview
by mengdong.lin＠intel.com 01 Nov '13

01 Nov '13

From: Mengdong Lin <mengdong.lin(a)intel.com> For Valleyview display codec, if an unused pin chooses an assgined converter selected by a used pin, playback on the unused pin can also give sound to the output device of the used pin. It's because data flows from the same convertor to the display port of the used pin. This issue is same as Haswell. So this patch avoids using assinged convertors for unused pins.

Changelog v4: * PATCH-3: Drop useless register configuration. * * Nothing changes for the other three patches v3: * PATCH-1: Add comments to indicate the end of v1 and v2 array. * PATCH-3: Use better way to keep watermark as even number. * * Nothing changes for PATCH-2 and PATCH-4 v2: * Instead of adding rogue scripts to current SDMA driver based on firmware * V1, we define the new SDMA firmware as version 2 and bisect the PATCH-1 * to two patches: The first is to add version check code to the SDMA driver; * And the second is to add SSI dual FIFO DMATYPE. * * Nothing changes for the last two patches. v1: * SSI can reduce hardware overrun/underrun possibility when using dual * fifo mode. To support this mode, we need to first update sdma sciprt * list, and then enable dual fifo BIT in SSI driver, and last update DT * bindings of i.MX series. * * ! This series of patches has a direct dependency between them. When * ! applying them, we need to apply to one single branch. Otherwise, * ! it would break currect branches.
