[alsa-devel] Repost: snd-hda-intel[ALC883] scratching and stuttering sound on MCP78S board
by Hans-Frieder Vogt 20 Jul '08

20 Jul '08

Hi List, This is just an updated repost of my request from a month ago. So far I have not achieved to solve the problem myselves, therefore I would very much appreciate ANY hint as to what (and even more important: where) to look for. Here is a summary of my problem and some related info: I am experiencing severely scratching and stuttering sound on my nVidia MCP78S (GeForce 8200) based Asus M3N78-EMH HDMI mainboard, which has an ALC883 on board, running with an Athlon X2 4850e dual-core CPU. It sounds, as if the sound buffers are not filled in time and are therefore repeated many times (2 to 4 times) per second. The problem seems to be kernel / alsa-driver related, because I experience the problem also when running runlevel 1 with only a minimum of active processes (e.g. without graphics). Strange enough, the sound is OK when I do a larger compilation in parallel (kernel make with make -j 2), but the sound is not OK when I run burnK7 (two instances to sufficiently load both CPU cores) => What is different in CPU loading or scheduling between these two load cases? Also, the sound is OK when I copy large files in parallel. Could it be related, that lspci gives me for all devices a latency of 0, even though the kernel message tell me that it was set to 64? I cannot change the PCI latency to another value via setpci. I am using Message Signal Interrupts for HD Audio, although switching it off also makes no audible difference.

[alsa-devel] softvol and snd_pcm_rewind() is broken
by Lennart Poettering 20 Jul '08

20 Jul '08

Heya! With 1.0.17rc3 snd_pcm_rewind() is broken for softvol as it seems: - Sometimes the sound becomes heavily distorted after such a seek: http://mailman.alsa-project.org/pipermail/alsa-devel/2008-June/008860.html - And snd_pcm_rewind() might return a value that is higher than was passed in, which as far as I understood should never happen: http://mailman.alsa-project.org/pipermail/alsa-devel/2008-April/007308.html These two issues might be caused by the same error. Takashi, Jaroslav, how can I bribe you into fixing this? I'd love to release my new PulseAudio version soon which heavily relies on snd_pcm_rewind(), but unfortunately the most important driver (hda with softvol) makes the most problems with it. :-( Lennart -- Lennart Poettering Red Hat, Inc. lennart [at] poettering [dot] net ICQ# 11060553 http://0pointer.net/lennart/ GnuPG 0x1A015CC4

[alsa-devel] Altec Lansing FX5051 USB Speakers
by Jeremy Nickurak 19 Jul '08

19 Jul '08

This didn't appear to make it through to the list when I tried a few days ago to send it, so I'll try again. --- It's been about 7 months since I last brought this up, and didn't really get any success at the time, so I thought I'd check and see if anybody has any insights again. About a year ago I posted my original request here for any suggestions in getting a set of USB speakers from Altec Lansing, model# FX5051, working with ALSA. They're a set of 5.1 speakers with a built in USB sound card. Sound does appear to work, but the mixer is locked at 100%. There is no analog manual mixer, and the digital control dial exhibits the same problem as alsamixer, so I have to find a way to adjust the usb device's mixer volume in order to make the speakers usable. The speakers work fine in Windows XP, without installing any drivers, so it would seem that this device is operating based on some standard. In windows, adjusting the mixer via the digital control dial, or via the windows mixer control both result in the LED display moving in sync to indicate the new volume setting. In alsa, adjusting the digital control dial doesn't appear to have any effect, other then waking the LED display from its low-light mode. Attempting to adjust volume from alsamixer likewise wakes the display from low-light mode, but also fails to significantly change the mixer setting. When I say significantly, I mean that the mixer flips between about 98% and 100%, when using the Up/Down keys (or PgUp or PgDown). End appears to drop the volume to 0%, but Home doesn't restore it. Pressing the device's 'Power' button also behaves strangely. I can turn the device off, but it is turned back on shortly afterward. No usb connect/disconnect events appear here, instead, the power button seems to function more like a mute. amixer -c 2 contents yields: atrus@kedri:~$ amixer -c 2 contents numid=3,iface=MIXER,name='Tone Control - Bass' ; type=INTEGER,access=rw------,values=1,min=0,max=10,step=0 : values=1 numid=4,iface=MIXER,name='Tone Control - Treble' ; type=INTEGER,access=rw------,values=1,min=0,max=10,step=0 : values=3 numid=1,iface=MIXER,name='PCM Playback Switch' ; type=BOOLEAN,access=rw------,values=1 : values=on numid=2,iface=MIXER,name='PCM Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=49,step=0 : values=48,48 | dBscale-min=-49.00dB,step=1.00dB,mute=0 I'm attaching the contents of 'lsusb -v'.

[alsa-devel] ASOC, master clock direction
by Jon Smirl 19 Jul '08

19 Jul '08

The MPC5200 has three clock configurations 1) Clock out, normal master mode 2) Clock in, normal slave mode 3) Something Freescale calls cellphone slave but it is more like clock distribution. In cellslave mode one i2s port is in normal slave mode. The clock from this port is used to drive up to three other i2s ports in master mode. I have two choices for set_sysclk: #define SND_SOC_CLOCK_IN 0 #define SND_SOC_CLOCK_OUT 1 When the clock frequency changes I need to notify the i2s drivers for the dependent channels. Do we need a third choice, SND_SOC_CLOCK_SLAVE? Alternatively I can use another clock id value. -- Jon Smirl jonsmirl(a)gmail.com

Attached are two high-res pix of the card. The smallest chips were just too darned small for me to read the printing; maybe you can magnify the pix and make something of them.

[alsa-devel] [PATCH] ASoC: Allow codecs to override register display
by Mark Brown 18 Jul '08

18 Jul '08

Some codecs have unusual features in their register maps such as very large registers representing arrays of coefficients. Support these codecs in the register cache sysfs file by allowing them to provide a function register_display() overriding the default output for register contents.
