[alsa-devel] when i plugin my headphone the sound come out from speaker and headphone
by Michael Domanski 05 Dec '09

Hi, When I plugin my headphone the sound come out from speaker and headphone. The speaker and headphone working in the same time. I want my speaker to mute when headphone is plugged. http://www.alsa-project.org/db/?f=841de9447634e7e35ae0171f968c70de253259af mixer@mdomansky ~ $ sudo lspci |grep -i "multi\|audio\|040[0-3]" 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) mixer@mdomansky ~ $ sudo rmmod snd-hda-intel mixer@mdomansky ~ $ sudo modprobe snd-hda-intel model=hp WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.

The following changes since commit a649d1fcc9bd2299cb06b6594fabb429fa50f174: Daniel Mack (1): ASoC: pxa/raumfeld: adopt new snd_soc_dai_set_pll() API are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git for-2.6.33 Very last minute but these would qualify as bug fixes during the release cycle so I feel comfortable merging them now.

[alsa-devel] What's in sound git tree for 2.6.33
by Takashi Iwai 04 Dec '09

04 Dec '09

Hi, here is the annual report of sound subsystem for 2.6.33. For 2.6.33, sound bits aren't crazy huge like 2.6.31 or 2.6.32. HD-audio stuff is getting stabilized, but still lots of changes. There are many small fixes here and there, including (not surprisingly) even ISA drivers. Large amounts of changes are found for the support of new VIA HD-audio codecs, Intel HDMI codecs, and a few new drivers and board-supports like Infrasonic Quartet support. In ALSA core side, there are a couple of important fixes. The all "PC Speaker" and "PC Beep" mixer elements are renamed to "Beep". This was a confusion for a long time, and hopefully more understandable now. And, a long-standing PCM mmap problem on PPC and MIPS non-coherent architectures is fixed -- or better to say, Oops is worked around. We are still looking for a saner solution, but it'll be likely an issue for 2.6.34. The biggest change in HD-audio is that we enabled MSI as default now. So far, there is no regression report by this. But, if you see any IRQ issues newly on the new kernel, please report. For ASoC, this has been another fairly quiet release, too. Aside from the addition of virtual mux support to DAPM and some further preparatory work for multi-CODEC cards the majority of changes have been driver updates, including: - New drivers for ADS117x, AK4671, TLV320DAC33, TPA6130A2, WM8711 and WM8727. - Substantial improvements to DMA performance and reliability on MPC5200 and DaVinci. - Capture support for the FSI port on SH. Due to cross tree merge issues some updates to the TWL4030 MFD code are also included, enabling sharing of the CODEC hardware by support for the VIBRA interface of the devices. The tree is at: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git for-linus The short log and diffstat are below.

[alsa-devel] Underruns in basic audio playback application
by Devin Heitmueller 04 Dec '09

04 Dec '09

Hello all, I am working on a very basic application that reads a capture device and outputs to a playback device. It's what you would traditionally accomplish with something like the following: arecord -D hw:1,0 -r 48000 -c 2 -f S16_LE | aplay - However, in this case, since the final result will be part of a TV watching application, I need to maintain less than 30ms of latency to preserve lipsync. The application I ended up with essentially creates two PCM streams (one for capture, one for playback), sets them up with the same parameters in terms of rate, format, channels, etc., and then has a loop of snd_pcm_readi() and snd_pcm_writei() calls. The application works, except I am getting a considerable amount of underruns on the playback device. Given my relative inexperience with alsa-lib, I suspect that I have misconfigured one of the parameters effecting buffering - buffer size, buffer time, period size, period time. Can anyone offer any constructive suggestions or tips on what these tuning parameters should be set to for a continuous 48000Khz, 2 channel stream of audio? Also, should the buffering configuration really be the same for both the capture and playback stream, or do I need to play some games such that one requires more/less buffering than the other? Thanks in advance, Devin -- Devin J. Heitmueller - Kernel Labs http://www.kernellabs.com

[alsa-devel] ALSA Control Questions
by Tobias Schneider 04 Dec '09

I've got some questions concerning the ALSA control interface... 1. What is a "simple" control? I would like to use the control interface to set more than just volume (e.g. I would like to set input gain, output attenuation, input channel selection, output channel selection, output channel activation...), so I am wondering if I should use SNDRV_CTL_ELEM_IFACE_CARD or SNDRV_CTL_ELEM_IFACE_MIXER, as they are obviously in context with "simple" control... 2. The more interesting question: as written in "Writing an alsa driver" callbacks are basically not atomic, but I am getting BUG: scheduling while atomic: amixer/0x00000001/430 Call Trace: .[..] in "put" callback?? So what is meant with "basically not atomic"?? What is allowed and what is not allowed, am I able to get hardware interrupts in this context?

[alsa-devel] [PATCH v2] ASoC: DaVinci: Update suspend/resume support for McASP driver
by Chaithrika U S 04 Dec '09

04 Dec '09

Add clock enable and disable calls to resume and suspend respectively. Also add a member to the audio device data structure which tracks the clock status. Tested on DA850/OMAP-L138 EVM. For the purpose of testing, the patches[1] which add suspend-to-RAM support to DA850/OMAP-L138 SoC were applied.

[alsa-devel] snd_hda_intel: MacBook Pro 5,1 / ALC889A issues
by Alexey Spiridonov 04 Dec '09

04 Dec '09

Hello, The hda_intel driver is only marginally usable on my laptop. I described the problems in detail here: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/488103 In brief, one has to choose between two sets of problems: 1) model=mbp3: broken speakers or 2) model=mb5: working speakers, but noisy headphone output Neither option provides headphone jack sense. Neither option is able to access the headset-type microphone available under MacOS through 3-band jacks like this: http://img.tomshardware.com/us/2007/07/19/how_good_is_apples_wired_iphone_h… (MacOS automatically switches from the in-computer mic to the the headset mic -- I haven't been able to get any signal from it despite trying all permutations of alsamixer's capture settings) I have attached the output of alsa-info.sh. I'd be happy to help test patches, or other debugging support. Thanks a lot! ~a

[alsa-devel] syslog says snd-usb-audio bug?
by Achilles H 04 Dec '09

04 Dec '09

Dec 4 00:16:21 susbwoy pulseaudio[1719]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Dec 4 00:16:21 susbwoy pulseaudio[1719]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers. Dec 4 00:16:21 susbwoy pulseaudio[1719]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. I am using Ubuntu 9.10 64bit with an Edirol UA-25 USB sound card. I installed OpenArena, and tried to open it. Screen went black - Could only get back to the desktop by killing X. This is what happened in the terminal when OpenArena Died at Initializing sound ------ Initializing Sound ------ bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) bt_audio_service_open: connect() failed: Connection refused (111) Allocated 96 sources. OpenAL default capture device is 'ALSA Capture on default' AL lib: alsa.c:675: set access failed: Invalid argument AL lib: oss.c:307: Could not open /dev/dsp: No such file or directory Killed I have no issues with sound at all apart from trying to use OpenAL.Warsow(another great game) will also refuse to run with OpenAL, except it runs great in the default sound mode 'qf'. What is going on here? thanks
