[alsa-devel] DMA interrupt not getting triggered
by ANISH KUMAR 05 Feb '10

05 Feb '10

I am facing problem related to DMA interrupt not getting triggered some times(out of 5 times one time it is happening) causing application to wait for the buffers(hw_ptr = 0) and no sound because of this. I am using samsung soc with DMA controller PL080.I tried increasing periods_min to 4 but still no result. I am using 2.6.29 kernel version.

[alsa-devel] ioctl problem - help please!!
by Rene E. Henriquez G. 04 Feb '10

04 Feb '10

Good day to everyone. I'm developing a system in which I need to gather some entropy from /dev/random. In order to increase the entropy, I'm using a daemon called audio-entropyd from Folkert van Heusden, but it has some problems that maybe you guys can help me with this. Does anybody know what might cause this: 2925 open("/dev/snd/pcmC0D0c", O_RDWR|O_NONBLOCK) = 5 2925 ioctl(5, 0x80184151, 0x7ffff3351890) = -1 EIO (Input/output error) to give EIO? The daemon just stops with the KILL signal. Thanks for reading this, I really need your assistance for this please. Regards, René.

[alsa-devel] [PATCH] ALSA: cosmetic: make hda intel interrupt name consistent with others
by Maxim Levitsky 04 Feb '10

04 Feb '10

This renames the interrupt name in /proc/interrupt. HDA Intel -> hda_intel This also eliminates space from the name, probably helping some parsers.

[alsa-devel] [PATCH] hda-analyzer: Avoid AttributeError when codec has no nodes
by Ozan Çağlayan 04 Feb '10

04 Feb '10

When traversing card/codec/nodes during treewidget creation, it's quite possible that codec.nodes raises an AttributeError if the current codec doesn't seem to have a nodes dictionary. Simply initialize it to an empty dictionary in the beginning of analyze().

[alsa-devel] ALC268 - Driving mute led with GPIO
by Ozan Çağlayan 04 Feb '10

04 Feb '10

Hi, We have a laptop here (a local brand) which has a mute button with a LED. Currently the mute button works correctly but the led is non-functional. I've played through hda-analyzer and found out that it's enabled when you enable gpio3 and click out_dir. Clicking out_dir again and again switches it on and off. There's a mute led stuff in patch_sigmatel, sigmatel_spec has gpio_led and gpio_polarity information but alc_spec doesn't have. How should we hook/patch that information into the codec? I'll try to send the alsa-info output tomorrow. Thanks. Ozan
