Herton and Takashi, I can confirm that compiling and installing the latest snapshot of alsa-drivers, adding "model=hp-dv5" to /etc/modprobe.d/alsa-base, and running hda-verb with the parameters Takashi indicates DOES result in sound from the onboard, internal speakers on my Hewlitt Packard dv4 1225 Pavilion Entertainment PC. The mute on headphone use does not work, but that's okay by me for now. I think you're on the right track in diagnosing the problem and it's solution. Thank you very, very much for helping us. I know it'll likely be a while before the solution actually makes it into distributions, but at the least I can use my sound apps without having to plug my laptop into something to hear what's playing. Kinda defeats the notion of having a laptop if one has to keep it plugged in. Do either of you mind if I collate notes from the posts exchanged on alsa-devel and post them on the Ubuntu forums? There are a lot of other HP users who have posted about the same problem. It's likely they have no idea the resource available to them in the alsa-devel archives.

[alsa-devel] ALSA SoC Architecture Document
by Anuj Aggarwal 17 Feb '09

17 Feb '09

Hi, I was looking for ASoC architecture document and came across a presentation done by Liam Girdwood for ASoC in Jan 2006 (http://www.embedded-kernel-track.org/2006/ASoC.pdf). But I could not find the presentation because the link has expired. Can someone share the presentation or any other ASoC specific architecture document, which can help someone understand the design and data/control paths? Thanks in advance Anuj Aggarwal

On 2.6.29, the delayed handling is done via its own workqueue, so this might be no longer a problem. Also you could try position_fix=1 instead of bdl_pos_adj. The problem is likely your hardware does unreliable DMA position reporting. Detecting such a broken hardware would be possible, but it'll be a bit tricky...

Thanks in advance. Thanks. Let me know if you find out a problem. OTOH, the fact that the native ALSA output works implies that it's rather an application-side problem...

However our G35 board can drive Yamaha directly in console. The i915 kernel module is irrelevant. Thanks, Fengguang

We bought the same Yamaha RX-V1800 and experienced the same problem. I was doing extensive (black box) debugging on it these days, and found that the following process can produce sound on Yamaha: startx xrandr --output HDMI-1 --mode 1920x1200 In fact the default 1920x540 mode is the only mode in which Yamaha cannot produce sound. Our intel gfx maintainer confirmed that it's actually the 1080i mode that is not supported yet. Thanks, Fengguang

[alsa-devel] dma buffer format
by York Sun 16 Feb '09

16 Feb '09

Takashi, I am now working on a surround sound driver for the first time. I am confused by the packed format of dma buffer. If the channel number is 6, is the buffer filled with data as front left, front right, rear left, rear right, center, LFE or front left, rear left, center, front right, rear left, LFE? Thanks, York

[alsa-devel] [PATCH] cs4236: cs4232 and cs4236 driver merge to solve PnP BIOS detection
by Krzysztof Helt 16 Feb '09

16 Feb '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> Also, the patch adds recognition if the chip is cs4236b+ or earlier part. This unifies drivers for both cs4232 and cs4236+ chips. It allows to use the PnP BIOS detection for the cs4236+ chips. Previously, only the snd-cs4232 could be detected by the PnP BIOS. The cs4232+ cards reports two separate PnP BIOS ids. The patch adds search for the second id to find out resources assigned to a control port. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- The cs4232 and cs4236 are the same now and one can be removed. Stanley tested this patch and it worked for him (cs4232 chip in Tecra 500). I have tested it on Dell Latitude CP (cs4237b chip) which is now correctly recognized. Previously, it was recognized as a basic cs4236 chip. Also, I have tested it with Maxi Sound 32 PnP card (ISA PnP cs4236b) with success. A side effect of this approach is that on ISA PnP cards the driver reports an error of PnP BIOS detection everytime it is loaded. This is due to driver rejecting the PnP BIOS initialization for ISA PnP cards. Probably, the earlier cs4232 driver worked the same way. diff --git a/include/sound/wss.h b/include/sound/wss.h index fd01f22..6d65f32 100644 --- a/include/sound/wss.h +++ b/include/sound/wss.h @@ -154,6 +154,7 @@ int snd_wss_create(struct snd_card *card, unsigned short hardware, unsigned short hwshare, struct snd_wss **rchip);

[alsa-devel] [PATCH] Workaround for misdetected sample rate with CM6207
by Joris van Rantwijk 16 Feb '09

16 Feb '09

Summary: Workaround for misdetected sample rate with CM6207 The CM6207 incorrectly advertises its 96 kHz playback setting as 48 kHz in its USB device descriptor. This patch extends an existing workaround in usbaudio.c to also cover the CM6207. This resolves issue 0004249 in the ALSA bug tracker.
