[alsa-devel] OSX Core Audio ASYNC OUT with rate feedback format ?
by Alex 01 Oct '10

01 Oct '10

Hi Daniel et al, I have successfully interfaced the sdr-widget with Linux alsa-driver for ASYNC OUT with rate feedback. Found out after much trial and error and reading of the usbaudio alsa-driver source code that you are using 12.13 as the format for the feedback rate !!! I was trying with 10.14 (UAC1 v1.2 specs , I think) in 3 bytes, and 16.16 (USB 2.0) in 4 bytes for quite a number of days with no success !!! However, 12.13 in 4 bytes, whilst working like a charm with Linux, does NOT work with OSX. Would you know the format used by OSX? Thanks. Alex

[alsa-devel] how many processed frames? + various thoughts
by John John 01 Oct '10

01 Oct '10

Hello all, I'm rather new to ALSA development. I would like to build a little loop-player driven by a beat counter and a good mail exchange from linuxaudio.org gave me a smart solution: to count the beat bars into the audio thread. Knowing the sample rate and the processed samples, I'm able to calculate the clock (what do you think about this approach?). And now my question: is there a good function into alsa API which returns the number of processed frames? Or even better, is it possibile to fire a callback after N frames? Thank you in advance (and sorry for my English)! JJ

[alsa-devel] [PATCH] ASoC: Remove -dai suffix from i.MX SSI driver
by Mark Brown 01 Oct '10

01 Oct '10

While it is a generic serial port in practice the i.MX SSI is only supported in Linux as an audio port (the i.MX has dedicated SPI controllers and so on). This means we don't need to disambiguate against other uses of the hardware and so can drop the -dai suffix from the driver name which fixes merge issues with the i.MX tree in -next.

[alsa-devel] unsupported variant of snd_hda_intel
by Alexandre 01 Oct '10

01 Oct '10

Hello, I have an Acer Aspire 4736G laptop. The soundcard that is shipped int his laptop is intel-hda based as shown: cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0x9b300000 irq 46 Basic sound output is correct but few feature are missing: - internal mic seems to be found but do not works. - sound output stop working when trying to send it using HDMI output - heads do not work when plugged neither when forcing pulseaudio to use it. I have an ubuntu 10.10 which is shipped with alsa 1.0.23. I have googled around and tried loading the snd-hda-intel with several parameters () as found in HD-Audio-Models.txt to no avail. cat /proc/asound/pcm 00-00: ALC888 Analog : ALC888 Analog : playback 1 : capture 1 00-01: ALC888 Digital : ALC888 Digital : playback 1 00-03: NVIDIA HDMI : NVIDIA HDMI : playback 1 Where can I begin to help implement the support for this sound card? I have very skills in developement in general but am ready to try if it is not to hard (I supose I can use previous code for similar models).. I just need a shepherd. Thanks

when i tried to use the PXA2xx specific driver for PXA3xx there are errors pointing to PXA3xx. i will capture the error and will publish here. thanks On Fri, Oct 1, 2010 at 9:19 AM, Mark Brown < broonie(a)opensource.wolfsonmicro.com> wrote: > On Fri, Oct 01, 2010 at 08:58:45AM +0530, Sayiram K N wrote: > > what i mean is under sound/soc/pxa/ i can see only pxa2xx-ac97 file but > not > > the sound/soc/pxa/pxa3xx-ac97 files which are required for pxa320. > > The IP is the same for both PXA2xx and PXA3xx so the same driver is > used. >
