[alsa-devel] Mixer control for signed gain value
by Patrick Lai 28 Jun '11

28 Jun '11

Hi, The CODEC I am working with takes byte-long gain value in two's complement form. In soc-core.c, the closest functions I see are snd_soc_info_volsw_s8 snd_soc_get_volsw_s8 snd_soc_set_volsw_s8 These functions are coded to work with two integer values. For my purpose, I suppose that I can always set 2nd integer input as zero. However, would I still be able to set volume like amixer sset "Codec Gain" 100 as percentage. If yes, how will amixer know to put upper 8 bits of 16 bit gain in 2nd integer value element? Thanks Patrick -- Sent by an employee of the Qualcomm Innovation Center, Inc.

[alsa-devel] [PATCH v3 1/3] ASoC: Add ADAV80x codec driver
by Lars-Peter Clausen 28 Jun '11

28 Jun '11

This patch adds support for the Analog Devices ADAV801 and ADAV803 audio codec. Signed-off-by: Lars-Peter Clausen <lars(a)metafoo.de> --- Changes since v2: * Allow to enable/disable SYSCLK outputs by using snd_soc_dai_set_sysclk Changes since v1: * Sync register on resume * Don't use arrays for the mux enums and controls * Rework PLL handling. Use DAPM for powering the PLL and OSC down and use set_sysclk to select the system clock instead of doing this implicitly in set_pll. --- MAINTAINERS | 1 + sound/soc/codecs/Kconfig | 4 +

[alsa-devel] Realtek ALC662 rev1 no sound over HDMI
by crow 27 Jun '11

27 Jun '11

I am trying to get sound working on kernel 2.6.39 (under archlinux x86_64 bit distribution) over HDMI to my digital receiver but without luck. Before this post i asked in #alsa for help, and everything we tried over there didnt get the sound over HDMI. I connected headphones to the green jack and ran speaker-test and there is sound over jack, analog sound plays fine. But runing alsamixer un-muting spdif/iec958/spdif (1) and trying to re run speaker-test doesn't output sound over HDMI to my digital receiver. I tried to use /etc/asound.conf for global settings (tooked from 2.6.35 archlinux i686 installation) but does not work with 2.6.39 installation, even I am not able to play analog sound: speaker-test -c2 -twav -l1 This above works without asound.conf, and it plays analog sound on headphones. This is how i tried to play sound over HDMI: speaker-test -c2 -D plughw:0,3 -twav -l1 The above command does output sound on 2.6.35 (but just over Fron Right) I run alsa-info.sh script on both installation and it can be found on (2) kernel 2.6.39 and (3) kernel 2.6.35. I was hoping to get sound working with 2.6.39 (current official archlinux kernel) over HDMI by just un-muting spdif with alsamixer, but it seems not to be that easy.

[alsa-devel] [PATCH] alsa: lx6464es - include mac address in device name
by Tim Blechmann 25 Jun '11

25 Jun '11

each device has a unique mac address, which can be used to distinguish multiple devices in the same machine. we therefore include the full mac address in the device shortname and the last 6 bytes in the device id.
