[alsa-devel] ALSA UCM

Hello, I recently cloned: git clone git://git.alsa-project.org/alsa-lib.git alsa-lib git clone git://git.alsa-project.org/alsa-utils.git alsa-utils and switched to the "ucm" branch to give it try. I have a panda board (pandaboard.org it is just a TI OMAP4 platform). I created some configuration files for my card. My conf file is 'SDP4430.conf' and my verb is on 'hifi'. I came with a simple program to set my verb and configure it for a simple device. I'm calling this sequence: 1. open it.... snd_use_case_mgr_open(&uc_mgr,"SDP4430") 2. reset it ....snd_use_case_mgr_reset(uc_mgr) 3. query for my verb.... snd_use_case_get_list(uc_mgr,"_verbs",&mylist) 4. set my verb ... snd_use_case_set(uc_mgr,"_verb",*mylist) 5. set my created device... snd_use_case_set(uc_mgr,"_enadev","Headset.0") 6. close it... snd_use_case_mgr_close(uc_mgr) Seems to work ok (without any errors) but I can't see any of my amixer controls set/changed accordingly to my verb/device. Is this a right sequence to follow? may be my files are not well written? Thanks for your help! Abraham

When you repost the series, you should collect any acks, sign-offs, tested-by etc. tags that others have reported. Mark, I assume you're OK with me merging this ASoC change via the davinci tree?

[alsa-devel] [PATCHv2 0/3] ASoC: Extend DAPM to handle cross-device paths
by Jarkko Nikula 12 Nov '10

12 Nov '10

Hi Here's updated version of previous RFC_ii/iv set: http://mailman.alsa-project.org/pipermail/alsa-devel/2010-October/033196.ht… Patches 1-2 have no remarkable changes, just modified on top of recent changes. Patch 3 is simpler as it turns out that the dapm_seq_run_coalesced doesn't need any changes because it's enough to call it with a right DAPM context. One fix is in beginning of dapm_power_widgets that d->dev_power is zeroed only for those codecs that have widgets in order to avoid unnecessary widgetless codec bias shutdowns. Minor changes are dapm.sys_power renaming to dev_power and long lines are cut. -- Jarkko

Hi , we are doing audio streaming using linux usb audio class interface . sometimes when we start usb audio streaming , we get first this error : ALSA sound/usb/usbaudio.c:354: frame 0 active: -75 which is followed by coninous loop of below messages : ALSA sound/usb/usbaudio.c:354: frame 0 active: -71 ALSA sound/usb/usbaudio.c:354: frame 0 active: -71 ALSA sound/usb/usbaudio.c:354: frame 0 active: -71 ALSA sound/usb/usbaudio.c:354: frame 0 active: -18 ALSA sound/usb/usbaudio.c:354: frame 0 active: -18 ALSA sound/usb/usbaudio.c:354: frame 0 active: -18 ...... and so on can i be suggested regarding the significance of error : -75 , and the way to resolve this error .

Re: [alsa-devel] [PATCH] ASoC: Add MAX98089 CODEC driver

I've not read this properly yet but on a first quick scan through this bears a more than passing resemblance to the MAX98088 driver - are there sufficient incompatibilities between the chips to warrant having a separate driver? http://datasheets.maxim-ic.com/en/ds/MAX98088.pdf would suggest not... Keeping a single driver means less code to maintain, which is generally a win. Variations between the parts can be accommodated by registering different controls and so on based on the I2C device ID that the system registers.

[alsa-devel] [PATCH v2 0/3] ASoC: Introduce the new caching API
by Dimitris Papastamos 11 Nov '10

11 Nov '10

This patch series introduces the new caching API. The idea behind this caching interface is that we can provide different means of organizing and accessing the register cache. This is useful for large and sparse register maps, where one can use some kind of compression algorithm to reduce the memory footprint. The caching API is designed in such way to eliminate the need for modifying any existing drivers. TODO: - Memory usage statistics, to make it easier to select the proper caching technique. - Support for bulk reads/writes. - Overridable caching behaviour from the machine driver. - Optimize certain CPU intensive paths. - Ensure proper locking in init()/exit()/sync(). Dimitris Papastamos (3): ASoC: soc-cache: Add support for flat register caching ASoC: soc-cache: Add support for LZO register caching ASoC: soc-cache: Add support for rbtree based register caching include/sound/soc.h | 29 ++ sound/soc/Kconfig | 2 + sound/soc/soc-cache.c | 984 +++++++++++++++++++++++++++++++++++++++++++++++-- sound/soc/soc-core.c | 37 +-- 4 files changed, 998 insertions(+), 54 deletions(-) -- 1.7.3.2
