[alsa-devel] Why is substream->pcm->dev == NULL?
by Timur Tabi 08 Aug '08

08 Aug '08

In my _pointer callback function, I have this: printk(KERN_INFO "%s:%u substream->pcm->dev=%p, substream->pcm->card->dev=%p\n", __func__, __LINE__, substream->pcm->dev, substream->pcm->card->dev); During playback, it displays this: fsl_dma_pointer:698 substream->pcm->dev=00000000, substream->pcm->card->dev=dfa50a08 Why is substream->pcm->dev == NULL? What's the point of having this field if you're not going to use it? -- Timur Tabi Linux kernel developer at Freescale

[alsa-devel] [PATCH] ALSA: fix DMA channel selection in Freescale MPC8610 sound drivers
by Timur Tabi 07 Aug '08

07 Aug '08

On the Freescale MPC8610, SSI1 is hard-coded to use DMA channels 0 and 1 for playback and capture, and SSI2 is hard-coded to use DMA channels 2 and 3. This patch fixes the fabric driver so that it uses the right channels.

[alsa-devel] Dell Studio 15 - aka Inspiron 1535 sound problems: HDA intel and codec IDT (STAC) 92HD73C1X5
by Andrea Venturi 07 Aug '08

07 Aug '08

hi, i own a brand new Dell laptop Studio 15 the audio speakers stay mute if i play an audio file. :-| i'm using debian lenny kernel. it seems to me a wrong port mapping. i put in place a newer Alsa 1.0.17 kernel modules with debug enabled, but still no sound. i append some relevant info about HW, alsa dmesg and codec description you can find more info about this laptop and the audio not workig here (look for audio support): http://www.avalpa.com/assets/andrea/studio15/debian_on_dell_studio15.html this is the dmesg detection WHEN i tried to remove the Subsystem Id: 0x10280254 autodetection (because it catches my subsystem albeit it says "unknown Dell"!) i'd really like to help more and try to solve myself the quirks of this new laptop but this NID stuff with the port/mixer configuration is really beyond a casual user workload. let me know if you need more info. bye andrea Venturi [36685.486337] ALSA

[alsa-devel] HDA Power management.
by Tobin Davis 06 Aug '08

06 Aug '08

Ok, I've been studying the code for a couple of weeks now, and testing on a mobile type development platform with a Realtek ALC262, but I have not been able to get the audio codec to enter low power mode (D3). I can see it switch when running that other OS. When running, the chip draws ~400mw, but drops to 40mw after switching to low power mode. How do I get it to do the same with the current driver? I'm using the git tip for alsa, and 2.6.26 final kernel. I have tried setting the power mode to D3 using the hda-tool from Takashi, but the codec reverts to D0 (full power) after a second or two, even though there is nothing touching the audio in my test environment. -- Tobin Davis The beauty of a pun is in the "Oy!" of the beholder.

[alsa-devel] [PATCH] ALSA: wss_lib: rework snd_ad1848_probe()
by Rene Herman 06 Aug '08

06 Aug '08

Hi Takashi. This reworks snd_ad1848_probe(), making for IMO significantly more straightforward reading. The original had a somewhat odd try-loop where it not only waited for the codec to come out of init but also retried a failed basic detect which seems to not make sense. Except for that, the detection logic should be unchanged. I am by the way rather unsure what it is that the spin_lock is trying to protect us from here. What's the error scenario if we just not take it? We aren't live yet... Next step is folding this into snd_wss_probe() directly. Rene.

[alsa-devel] [PATCH] ALSA: ASoC V2: Improve pause/unpause performance in Freescale 8610 drivers
by Timur Tabi 06 Aug '08

06 Aug '08

Add support for true pause and unpause. Without this, mplayer will drop some audio (less than one second, but still noticeable) when pausing playback. Remove support for PM suspend and resume from the trigger function, since the driver doesn't support PM anyway. Optimize the delay after starting capture. Instead of delaying 1ms, the driver now polls the hardware. The new delay is shorter by over 90% yet still effective.

End of this function is good check point of correct detection for ad1848 chips, 2. The snd_wss_probe() is long enough. But I won't oppose it fiercely.
