[alsa-devel] ice1724 - TerraTec PHASE 22 no MIDI ports get created
by Vedran Miletić 26 Aug '08

26 Aug '08

Hi guys, There was "MIDI on ice1724" thread not-so-recently, and it had a patch attached. Changelog says that the patch was added to ALSA in 1.0.17. So I took out my dusty TerraTec PHASE 22 out of the closet (and removed the dust, of course :-) ), but I can't get MIDI to work there. Regardless of ALSA version (1.0.15 - 1.0.17, even 1.0.18rc1), I get no MIDI ports at all: vedran@kalopsia:~$ amidi -l Dir Device Name vedran@kalopsia:~$ Why don't MIDI ports get created? I tried looking at the source, but I couldn't figure out how this "creation of midi ports" happens (or doesn't happen, as in this case). -- Vedran Miletić

[alsa-devel] OSS emulatior can not create enough device files for me
by Taipei Techwell 26 Aug '08

26 Aug '08

Hi, I am working on an ALSA audio driver for my device which is very similar to BT878. It will have at least 8 audio devices in a single card. Now, the audio driver is working correctly. I can use aplay to play the audio file which is created by arecord. To identify audio devices, I am using hw:1 ~ hw:8 dvice description for my audio devices, because hw:0 is the sound card. In order to make the old application work, I know that ALSA emulates all my devices to have OSS nodes respectively. I guess that It should have /dev/dsp to /dev/dsp8, and /dev/dsp is for sound card, and /dev/dsp1 to /dev/dsp8 are for my audio devices. However, I can not find /dev/dsp8 in my system. I guess ALSA can only emulate 8 audio device totally. That the reason I can not see the 8th audio device. Am I right? How can I create the /dev/dsp8 manually? By the way, if someting is wrong above, please correct me. Thank you.

[alsa-devel] [PATCH] ASoC: WM8903 I2C cleanups
by Mark Brown 26 Aug '08

26 Aug '08

Fix a few issues identified by Jean Delvare: - Add missing newline to error display. - Return an error when we fail to locate the I2C adaptor. - Remove the static wm8903_i2c_device Jean suggested, it's redundant.

[alsa-devel] [PATCH] ASoC: Fix double free and memory leak in many codec drivers
by Mark Brown 26 Aug '08

26 Aug '08

From: Jean Delvare <khali(a)linux-fr.org> Many SoC audio codec drivers have improper freeing of memory in error paths. * codec is allocated in the platform device probe function, but is not freed there in case of error. Instead it is freed in the i2c device probe function's error path. However the success or failure of both functions is not linked, so this could result in a double free (if the platform device is successfully probed, the i2c device probing fails and then the platform driver is unregistered.) * codec->private_data is allocated in many platform device probe functions but not freed in their error paths. This patch hopefully solves all these problems.
