[alsa-devel] [PATCH] ALSA: soc - fsl_ssi.c fix audio capture
by Anton Vorontsov 21 Jul '08

21 Jul '08

Since we're using SSI in synchronous mode, the STCCR register controls both the receive and transmit sections. So, when we're trying to record anything, stccr register does not get initialized, thus the output file filled with the white noise. Fix this by initializing the STCCR for both playback and capture. If TX/RX widths don't match, return that we're busy at the moment.

[alsa-devel] ASOC and 12 bit volume control
by Jon Smirl 21 Jul '08

21 Jul '08

How do I define a volume control that is the bottom 12 bits of a 32 bit register? #define SOC_SINGLE_VALUE(reg, shift, max, invert) ((reg) | ((shift) << 8) |\ ((shift) << 12) | ((max) << 16) | ((invert) << 24)) This looks like it only support an 8 bit max. Is there another way to do it? -- Jon Smirl jonsmirl(a)gmail.com

For the first step alsa-lib is upgraded in svn. I am very busy at the moment and will see what I can do nest week. My goal: Upload latest in week 31. Elimar -- Numeric stability is probably not all that important when you're guessing;-)

[alsa-devel] [PATCH] wss: fix capture formats limitations
by Krzysztof Helt 20 Jul '08

20 Jul '08

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> Fix copy-paste error with Interwave instead of ad1848 chip condition. Limit opti93x cards capture formats to only linear ones. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- Thank you Rene for collecting, testing and reviewing my patches. I found one mistake in the series and this patch fixes it. I have also limited capture formats for opti93x chips because the opti93x manual states that it supports mu-law, a-law and ADPCM decompression. The word "decompression" probably suggest that compression (recording) is not possible as its manufacturer could just state the card supported mu-law, a-law and ADPCM.

[alsa-devel] [0/2] Jack reporting
by Mark Brown 20 Jul '08

20 Jul '08

This is a repost of the the jack reporting API I posted recently. There are no chances since the last submission - as discussed in that thread the existing users and the need to support buttons implemented in jacks pushes me towards use of an input device to represent jacks.

[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
