[alsa-devel] Alsa io plugin crash question
by Hermes Zhang 16 Nov '16

16 Nov '16

Hi all, I am try to write a plugin in alsa io plugin mode static snd_pcm_sframes_t my_read (snd_pcm_ioplug_t * io, const snd_pcm_channel_area_t * areas, snd_pcm_uframes_t offset, snd_pcm_uframes_t size) { } In above function, I will copy the audio data to areas with calculate the offset like this: memcpy((char *) areas->addr + (areas->first + areas->step * offset) / 8, data, size); But after serveral calls, the application crash, and I print the "offset" value, it seem always increase, when reach one number (e.g. 66560) it crash. So my question is: is the "offset" value always increase is expected? Or does it should like a ring buffer, so it should start from begin again? I see there is hw_pointer and app_pointer, but they are both read_only, right? How could we adjust the read pointer? Thanks. BTW, I test the plugin in this way: arecord -D my_plug -c 1 -f S16_LE raw Best Regards, Hermes

[alsa-devel] [RFC PATCH 0/3] Add support for component devices
by mengdong.lin＠linux.intel.com 16 Nov '16

16 Nov '16

From: Mengdong Lin <mengdong.lin(a)linux.intel.com> Sound cards are defined by machines. And off-soc codecs and DSPs embedded in DSP can be taken as the components and resued by different machines/ sound cards. This series allows codec and SOC vendors to install UCM configuration files for a specific codec or DSP, and sound card verb files can just include these conf files of components, and trigger enable/ disable sequence defined by the component devices. Component devices will not be exposed to applications for backward compatibility. So audio servers like PulseAudio and CRAS still only see the machine devices.

[alsa-devel] [PATCH v9 0/3] ASoC: MT8173 HDMI jack detection
by Philipp Zabel 16 Nov '16

16 Nov '16

Hi, now that a new HDMI state notifier RFC has been posted [1], I've updated this series to use it instead of the previous prototype. I've also sent the drm/mediatek part of this series separately [2], which is needed to actually generate the events the hdmi-codec driver listens for. Changes since v8: - Dropped the HDMI notification prototype patch - Rebased onto the "video: add HDMI state notifier support" patch by Hans Verkuil, based on Russell King's earlier version. - Dropped the drm/mediatek patch regards Philipp [1] https://patchwork.linuxtv.org/patch/38109/ [2] https://patchwork.kernel.org/patch/9430337/ Philipp Zabel (3): ASoC: hdmi-codec: use HDMI state notifier to add jack support ASoC: mediatek: Add jack detection support to mt8173-rt5650-rt5676 machine driver ASoC: mediatek: Add jack detection support to the mt8173-rt5650 machine driver include/sound/hdmi-codec.h | 7 ++ sound/soc/codecs/Kconfig | 1 + sound/soc/codecs/hdmi-codec.c | 107 +++++++++++++++++++++-- sound/soc/mediatek/mt8173/mt8173-rt5650-rt5676.c | 42 +++++++++ sound/soc/mediatek/mt8173/mt8173-rt5650.c | 42 +++++++++ 5 files changed, 191 insertions(+), 8 deletions(-) -- 2.10.2
