[alsa-devel] plughw and hw
by hong zhang 13 May '11

13 May '11

Takashi, Last e-mail, you mention do not use plughw but hw. I compare both of them. And wonder which way is correct to capture multiple pins. my HDMI has 4 pins 1. HW failed with "-c 8" # arecord -f dat -d 5 -D hw:0,1 -c 8 05-12-new-hw-3pins.wav Recording WAVE '05-12-new-hw-3pins.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Channels 8 arecord: set_params:1059: Channels count non available 2. HW collect data for all 4 pins without "-c 8" 3. plughw with "-c 8" but only first pin has data inside 2 channels. The rest pins collect 0 data. 4. plughw collects data for all pins without "-c 8" why "-c 8" would not work right? Thanks. ---henry

[alsa-devel] GR-55 Driver
by Jeffrey Scott Flesher Gmail 12 May '11

12 May '11

I need a Driver for the Roland GR-55 Guitar Synthesizer, not sure how to get started, so I thought this would be a good place to ask. The GR-55 has MIDI and AUDIO KSNAME_Wo11="WaveOut1-1" WDM.Wo11.szPname="OUT (GR-55)" KSNAME_Wi11="WaveIn1-1" WDM.Wi11.szPname="IN (GR-55)" KSNAME_Md11="Midi1-1" WDM.Md11.szPname="GR-55" My thinking is that there may be a driver that is similar, or someone could already be working on a driver, if so, I would like to find out if I could work on that project or if I could start a new project here. I did contact Roland about getting help in the way of Documentation; but was told not to count on it since most of this documentation is proprietary; so I might end up having to snoop the information to reverse engineer it. I have been a programmer for over 30 years, and have written Unix drivers and interfaces back in the 80's; things have changed since then and Linux is Unix like, but ALSA seems a lot easier than what we did back in those days. I can get up to speed with just a point in the right direction. Things like do I do this as a driver or a module? Are just a few questions that I need answers to, just to get started. Can you recommend a driver that is close enough to use as a template to start a new driver from? Thanks. Jeff Flesher

[alsa-devel] [PATCH 0/6] ASoC: OMAP4: Add support for HDMI audio
by Ricardo Neri 12 May '11

12 May '11

This is to add support for HDMI audio on OMAP4 chips. This work has two parts: DSS implementation and ASoC implementation. This set of patches presents the ASoC implementation. The approach is to utilize the DSS HDMI driver to act as an ASoC codec. This set of patches adds the ASoC CPU DAI and machine drivers. These drivers will utilize the ASoC HDMI codec provided in the DSS HDMI driver. DSS part of the implementation is currently under review in the linux-omap list. The DSS HDMI driver controls the availability of HDMI output and audio can be played only when the HDMI video device is enabled and the video timing in use is one of the CEA-861-D video timings supported by the OMAP4 HDMI IP. This implementation is for Basic Audio as defined in CEA-861-D: 16 bit/sample linear PCM 2-channel audio with sample rates of 32, 44.1 and 48kHz. As described in the HDMI specification, support for Basic Audio is mandatory for HDMI sinks and does not require of EDID parsing. Additionally, this implementation supports 24-bit samples in 32-bit words. Further audio capabilities such as more sample rates and multichannel audio will be added in the future when EDID parsing is available for HDMI driver. This implementation is based on on: * OMAP4: DSS2: Add dss_dss_clk opt clock for OMAP4, by Sumit Semwal (http://gitorious.org/linux-omap-dss2/linux/commit/0da5637569bb9bf93e6930cd1…) * Kernel 2.6.39-rc6 (git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git v2.6.39-rc6) * v4 of OMAP4: DSS2: HDMI: Add support for audio git://gitorious.org/omap-audio/linux-audio.git ricardon/topic/hdmi-audio-v1 In order to validate functionality, it is necessary to utilize the DSS HDMI ASoC codec. The complete implementation, DSS and ASoC parts, is available at: git://gitorious.org/omap-audio/linux-audio.git ricardon/topic/hdmi-audio-v1 Validation was performed on HDMI TV. Penguins were present on the display and audio playback was performed with aplay at 32, 44.1 and 48kHz with S16_LE and S24_LE sample formats. Validation was performed on SDP4430 ES2.1 and Panda ES2.1 and ES2.0.
