[alsa-devel] ALSA: usb-audio: work around Anroid accessory firmware bug
by Clemens Ladisch 17 Jun '13

17 Jun '13

When the Android firmware enables the audio interfaces in accessory mode, it always declares in the control interface's baInterfaceNr array that interfaces 0 and 1 belong to the audio function. However, the accessory interface itself, if also enabled, already is at index 0 and shifts the actual audio interface numbers to 1 and 2, which prevents the PCM streaming interface from being seen by the host driver. To get the PCM interface interface to work, detect when the descriptors point to the (for this driver useless) accessory interface, and redirect to the correct one.

[alsa-devel] Timestamps using I/O Plugin
by Johan Hellman 17 Jun '13

17 Jun '13

I was excited when I found that it was possible to write user space drivers for ALSA, but I can't get my head around how timestamping works when using a I/O plugin instance. I better start explaining what we want to do. Basically we just want to transfer raw audio between the HOST running ALSA and one or more small(tiny) network connected MCUs with audio codecs. We need to synchronize the different network sources with the local HW sources (on the ALSA HOST). Starting looking into how timestamps is handled by ALSA I could not find how it was possible to set the timestamp, there seems to be some differences compared to using a normal kernel driver!? If I understand it correctly timestamp can be obtained by calling snd_pcm_status() but the ioplugs implementation of the .status() newer fills in the ->tstamp only the ->trigger_tstamp, so how can I set the timestamp of the data my plugin delivers to ALSA? Additionally snd_pcm_htimestamp() only seams to return the current monotonic clock at the point the function was called for an ioplug instance!? I saw that there are plugins for pulseaudio and jack doing what we whant to achieve but because of the footprint of the MCU we can't use PA/Jack on these MCU:s. But how have they solved this issue or isn't it an issue for their usecase? /JohanHellman

[alsa-devel] [ALSA] Codec Registration after soc_probe ()
by Rajan Vaja 14 Jun '13

14 Jun '13

Hi, My codec is registered after SOC init is done (sdp4430_init()). In soc init, ALSA cannot find codec registered (given in SOC dai) and hence it defers sound card registration. Later on codec is registered successfully but sound card registration is not done again. Is there any way to register codec later? I am using kernel version 3.4.0 with OMAP Panda. Thanks, Rajan

[alsa-devel] Raspberry Pi + Bluetooth Headset + Broadcom adapter
by Alexander Winnig 14 Jun '13

14 Jun '13

Hello. I want to give you a short summary of what I'm doing and what I'm trying to achieve: I have a Bluetooth headset "Iqua BHS-611" ( http://www.iqua.com/sites/default/files/product/iqua_slim_4.png ) and a Belkin USB adapter( http://www.amazon.co.uk/Belkin-USB-4-0-Bluetooth-Adapter/dp/B009IQB3US ). I can hear A2DP-transmitted audio on my headset. But when it comes to using the microphone I record zero bytes on a regular basis using parecord -r -d bluez_source.<whatever mac address> test.wav No error output, just a zero byte test.wav. Trying to use paplay to play a file(I tried 8000 Hz, 44,100 Hz files I created using another application, which contained audio data) also doesn't work using the HSP. Using the A2DP again, there is no problem. On your " contact us" - page ( http://bluetooth-alsa.sourceforge.net/contact.html ) you wrote > You might be able to get a broadcom adapter to work but it may require > that you boot with a kernel argument (the force_scofix parameter of > the hci_usb driver?) to > force sco mtu values I do have a Broadcom adapter, the belkin one. But I am using the raspberry pi, which only has a cmdline.txt for kernel parameters. I added force_scofix=1 but that didn't change anything. So now I am back to > dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 > console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline > rootwait for cmdline.txt. How can I make sure, that the reason is really the broadcom adapter, so I won't buy a new one in vain? After all A2DP is working. PS: Plugging in the Bluetooth adapter into an USB port of a computer that is running Windows 7 and installing the drivers that were included on the included CD-ROM, I can use all functionality of the headset, I can use the microphone just as a normal microphone in the microphone's list, I can use the stereo audio output, everything works.
