[alsa-devel] [PATCH 3/3] ASoC: SDP3430: Connect twl4030 voice DAI to McBSP3
by Lopez Cruz, Misael 18 May '09

18 May '09

Connect twl4030 voice DAI to McBSP3 in sdp3430 machine driver. Audio and voice DAI init functions are enabling corresponding interface by writting directly to AUDIO_IF and VOICE_IF codec registers, respectively.

[alsa-devel] Output frequency configuration for I2S in beagleboard? (underrun problem)
by Ernesto Torres 18 May '09

18 May '09

Hi, I would like to know the actual configuration for the output of the Beagle Board I2S, from the OMAP35x Reference Manual, on page 2887: • Enable the Sample Rate Generator (take it out of reset). Set McBSPi.MCBSPLP_SPCR2_REG[6] GRSTbit to1 to enable the Sample Rate Generator. After the Sample Rate Generator is enabled, wait for 2 CLKG cycles for the Sample Rate Generator logic to stabilize. * On the next rising edge of CLKSRG, the CLKG signal transitions to '1' and starts clocking with a frequency equal to (input clock frequency)/(CLKGDV + 1).* • If necessary, enable the receiver and/or the transmitter. It says the clocking will start with the frequency of input clock (I thougth it is 26Mhz but i've been told is 96Khz, not quite sure) and CLKGDV is a variable number to get a desired frequency. from omap-mcbsp.c: *static int omap_mcbsp_dai_set_clkdiv(struct snd_soc_dai *cpu_dai, int div_id, int div) { struct omap_mcbsp_data *mcbsp_data = to_mcbsp(cpu_dai->private_data); struct omap_mcbsp_reg_cfg *regs = &mcbsp_data->regs; dbg("omap_mcbsp_dai_set_clkdiv START"); if (div_id != OMAP_MCBSP_CLKGDV) return -ENODEV; dbg("div: %d",div); regs->srgr1 |= CLKGDV(div - 1); dbg("omap_mcbsp_dai_set_clkdiv END"); return 0; }* Here, the value is asigned to srgr1. I capture all actions from startup and from aplay but this function is never called. Do you know when it should be called or where we can find the div value? I'm having trouble adapting an external codec from the beagle, and I think it may be because of the output frequency from the beagle. I'm getting some underruns during playback(with aplay) and I don't know exactly where to begin. Suggestions are welcome. Thanks for your help Best regards, Ernesto

This patch adds support for MacBook 3,1 sound by adding a model new "mb31" with the appropriate init verbs, mixers and channel modes to the ALC883 configuration. patch_alc882() and patch_alc883() are modified to handle the MacBook 3,1 sound-chip (Realtek ALC889A) correctly.

[alsa-devel] Problems with maintaining a separate alsa-driver in a distribution
by Ozan Çağlayan 18 May '09

18 May '09

Hi, I'm maintaining the ALSA stack as a separate alsa-driver using the supplied tarballs from www.alsa-project.org unlike some popular distros which uses the in-kernel sound/ stack. This has the advantage of quickly acting against latest quirk or driver support changes and pushing a driver update instead of whole the kernel update. But there is a big disadvantage that I'm not able to figure out how to solve: When we enable the SND Kconfig option in kernel, some other sound support for some DVB devices(e.g. SAA7134 sound support, etc.) are enabled as well. So if you're using the in-kernel ALSA, you can enable and use them happily but in my case, those additional sound supports can't be enabled in kernel. Is there a way to hack around this when a separate alsa-driver is used in a distro? Is it technically possible to patch those tiny drivers onto alsa-driver and compile them if the .config file from the kernel source has enabled those DVB devices? Or maybe I should enable ALSA in-kernel, compile those DVB sound stuff and remove the sound/ directory from the kernel package? (Even the idea sounds really *dirty*, dunno if it's technically possible too) Thanks, Ozan Caglayan http://www.pardus.org.tr/eng

[alsa-devel] [PATCH 0/1] Improved MacBook 3,1 support
by Torben Schulz 18 May '09

18 May '09

Hi guys, this patch improves the support for the MacBook 3,1, which had been handled by the "mbp3" model before. The "mbp3" model is quite inappropriate for the sound-chip of the MacBook 3,1 (RealTek ALC889A). Especially the lack of subwoofer support is one of the biggest disadvantages of this model (See bug 0004086). In contrast to the other models this model is part of the ALC883 configuration, which reflects the ALC889A sound-chip far better than the ALC882 configuration, which all other Apple models are part of. I myself own only a MacBook 3,1, but as far as I know it should also work for the MacBook 4,1 - perhaps even for other models. It would be good if someone could check this out... The new MacBook 3,1 model is called "mb31" and has the following features: - sound from the third speaker (aka "subwoofer") - 5.1 surround sound - speakers and subwoofer are muted when headphones are plugged in. - 4 channel modes - 2ch: speakers:front, subwoofer:CLFE, headphones:front, line:input - 4ch: speakers:front, subwoofer:CLFE, headphones:front, line:CLFE - 5ch: speakers:front, subwoofer:CLFE, headphones:rear, line:input - 6ch: speakers:front, subwoofer:off, headphones:rear, line:CLFE However, there are also two "issues": Speaker will be unmuted, when channel-mode is changed while headphones are plugged in. But this can easily be solved, by plugging the headphones out and in again or using the speaker switches in the mixer. I haven't managed to get "real" surround sound. It seems that the front channel is mapped to all other channels before they get to the mixers (front-left=front-left, front-right=front-right, rear-left=front-left, rear-right=front-right, LFE=front-right, center=front-right). The volume of each channel can be set individually through the mixer. However, this could also be an high configuration issue on my side (please tell me ^^)... Bai Torben

[alsa-devel] [PATCH 2/3] ASoC: TWL4030: Add control for selecting codec operation mode
by Lopez Cruz, Misael 18 May '09

18 May '09

Add a control for selecting the codec operation mode. TWL4030 codec has two modes: - Option 1. Audio only (4 audio DACs) - Option 2. Voice/Audio (2 audio DACs and voice ADC/DAC) Control is restricted when a stream is ongoing, since codec's operation mode cannot be changed on-the-fly.
