[alsa-devel] [PATCH 0/2]ASoC: TWL4030 and SDP3430 HS ramp configuration
by Peter Ujfalusi 22 May '09

22 May '09

Hello, The following series adds support for platform dependent Headset pop removal configuration for the twl4030 codec. Platform drivers can fill the twl4030_setup_data structure and pass it with snd_soc_device->codec_data to the codec driver. As an example - based on the feedback for the ramp_delay value variations - the sdp3430.c board is updated to pass the correct ramp settings. If you know for the other platforms using the twl4030 codec the correct HS ramp configuration, please update those files... Mark: This series needs the DAPM restructuring and HS pop removal related patches for twl4030 codec. --- Peter Ujfalusi (2): ASoC: TWL4030: Add support for platform dependent configuration ASoC: SDP4030: Use the twl4030_setup_data for headset pop-removal sound/soc/codecs/twl4030.c | 22 +++++++++++++++++++--- sound/soc/codecs/twl4030.h | 5 +++++ sound/soc/omap/sdp3430.c | 7 +++++++ 3 files changed, 31 insertions(+), 3 deletions(-)

[alsa-devel] Program blocks with alsa pulse plugin
by Cristian Morales Vega 21 May '09

21 May '09

I'm not sure where exactly the problem is, probably in the alsa pulse plugin? And not sure where alsa pulse plugin should be reported, ALSA or PA? Using http://byuu.org/bsnes/ through the ALSA API with PulseAudio at some point provokes the game to block with 100% CPU usage. Stopping it I get this backtrace: Program received signal SIGTSTP, Stopped (user). 0x00007ffff2b8a386 in poll () from /lib64/libc.so.6 (gdb) bt #0 0x00007ffff2b8a386 in poll () from /lib64/libc.so.6 #1 0x00007ffff72ac94c in snd1_pcm_wait_nocheck () from /usr/lib64/libasound.so.2 #2 0x00007ffff72accb7 in snd1_pcm_write_areas () from /usr/lib64/libasound.so.2 #3 0x00007ffff72ebf3a in snd_pcm_ioplug_writei () from /usr/lib64/libasound.so.2 #4 0x000000000043e1b8 in ruby::AudioALSA::sample (this=<value optimized out>, left=<value optimized out>, right=<value optimized out>) at lib/ruby/audio/alsa.cpp:101 #5 0x000000000043ed8b in ruby::AudioInterface::sample (this=0x74c520, left=<value optimized out>, right=<value optimized out>) at lib/ruby/ruby_audio.cpp:110 #6 0x00000000004a5b82 in SNES::sDSP::enter (this=0x8528c0) at dsp/sdsp/sdsp.cpp:199 #7 0x00000000004a309a in SNES::sSMP::op_read (this=0x851860, addr=4532) at smp/ssmp/timing/timing.cpp:8 #8 0x00000000004a2652 in SNES::sSMP::enter (this=0x851860) at smp/core/memory.hpp:2 #9 0x000000000043bec0 in ?? () at lib/libco/x86-64.c:31 #10 0x0000000000000000 in ?? () There are lots of snd_pcm_writei() (lib/ruby/audio/alsa.cpp:101) calls before bsnes blocks, and the only errors are some underruns that are "fixed" with snd_pcm_recover(). Just that at some point (easier to trigger with 150% or 200% emu speed) blocks. It's using the "safe ALSA" everywhere, so... This is with openSUSE 11.1. But also with openSUSE 11.1 + PA from multimedia:libs (0.9.14) and a recent GIT snapshot of ALSA from multimedia:audio:snapshot and multimedia:audio:KMP. There is a package for Fedora in rpmfusion, and they have a readme that states the problem also happens there. To avoid this bsnes dev created a native PA backend. I inform just in case this is triggering a bug, perhaps affecting other software, you are interested in fix... PS. ...obviously bsnes never blocks when using ALSA directly.

What is the problem? I really want to know if it's about to be fixed. I'm getting tired of having no sound. https://qa.mandriva.com/show_bug.cgi?id=49048 /Kristoffer

[alsa-devel] [PATCH 0/2] ASoC: TWL4030: DAPM restructuring and Headset pop-attenuation fix
by Peter Ujfalusi 21 May '09

21 May '09

Hello, The following series aims to fix the Headset power on/off pop noise problems. Since the twl4030 codec internal implementation have this order in HW: DAC -> Analog PGA -> Mixer While the ASoC framework expects the following order: DAC -> Mixer -> Analog PGA I needed to move the APGA control from SND_SOC_DAPM_PGA to be handled with _MIXER. Than adding a PGA to the headset outputs results correct power sequences. This patch also separates the analog and digital loopback paths, so when the analog loopback is enabled none of the DACs will be powered on, while in case of digital loopback the corresponding DACs will be powered. These are internal changes, not visible for the user. I have tested it with my custom board with the headset soldered to HeadsetL, the pop noise is really small if any. The user must also set the correct ramp delay for the given board. On my board: MCLK = 38.4MHz RAMP_DELAY = 2 (109/81/55 ms) works best (meaning 55ms ramp delay), if it is shorter, than it clicks, if it is longer, than it does not click, but the beep tone can be observed. I hope that I have not missed anything with the patches, since these are forward ported from my working tree to sound-2.6:topic/asoc. I have applied the patch from Misael on top of the current topic/asoc, so the head was: ASoC: TWL4030: Enable/disable voice digital filters I believe that this should be able to minimize the pop noise on the headset outputs. --- Peter Ujfalusi (2): ASoC: TWL4030: Change DAPM routings and controls for DACs and PGAs ASoC: TWL4030: Move the Headset pop-attenuation code to PGA event sound/soc/codecs/twl4030.c | 257 ++++++++++++++++++++++++++++---------------- 1 files changed, 162 insertions(+), 95 deletions(-)

[alsa-devel] Testers wanted: New SB X-Fi driver
by Noel Bourke 21 May '09

Hi Takashi, I set this up with an Auzentech X-Fi Prelude. Driver works OK but sound seemed a bit off. According to speaker-test I seem to only have one audio channel! Any thoughts? Regards, Noel

[alsa-devel] Testers wanted: New SB X-Fi driver
by Marcel Mulders 20 May '09

20 May '09

Hi Takashi, I tried the snd-ctxfi driver on Ubuntu Jaunty x64. Seems to work just fine for me. Audacious and Totem have no problems as far as I can see. Great work, your efforts are very much appreciated! I was wondering, is there any chance to get the headphones-output on the frontpanel working? I don't really need all the other jacks to work, just plain old analog stereo.. ;-) In one of the closed-source drivers from Creative from a year ago or so, version 1.18, that worked fine. In the opensource driver from last February, the headphones were broken again, just like with the latest snapshot alsa drivers. Can you comment on this maybe? Thanks in advance. Marcel
