2010-07-12sound: push BKL into open functionsArnd Bergmann
This moves the lock_kernel() call from soundcore_open to the individual OSS device drivers, where we can deal with it one driver at a time if needed, or just kill off the drivers. All core components in ALSA already provide adequate locking in their open()-functions and do not require the big kernel lock, so there is no need to add the BKL there.

2010-07-12ALSA: via82xx: allow changing the initial DXS volumeClemens Ladisch
As per-stream volume controls, the DXS controls are not intended to adjust the overall sound level and so are initialized every time a stream is opened. However, there are special situations where one wants to reduce the overall volume in the digital domain, i.e., before the AC'97 codec's PCM volume control. To allow this, add a module parameter that sets the initial DXS volume. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Tested-by: Soeren D.

2010-06-28sis7019: fix capture issues with multiple periods per bufferDavid Dillow
When using a timing voice to clock out periods during capture, the driver would slowly loose synchronization and never catch up, eventually reaching a point where it no longer generated interrupts. To avoid this situation, the virtual period clocking was changed to shorten the next timing period when our timing voice falls too far behind the capture voice. In addition, the first virtual period for the timing voice was slightly too short, causing the timing voice to initially be ahead of the capture voice. While tracking down this problem, I noticed that the expected sample offset was being incorrectly initialized, causing an overrun to be incorrectly reported when the timing voice happened to be perfectly synchronized.

2010-06-28ALSA: pcm_lib: avoid timing jitter in snd_pcm_read/write()David Dillow
When using poll() to wait for the next period -- or avail_min samples -- one gets a consistent delay for each system call that is usually just a little short of the selected period time. However, When using snd_pcm_read/write(), one gets a jittery delay that alternates between less than a millisecond and approximately two period times. This is caused by snd_pcm_lib_{read,write}1() transferring any available samples to the user's buffer and adjusting the application pointer prior to sleeping to the end of the current period. When the next period interrupt occurs, there is then less than avail_min samples remaining to be transferred in the period, so we end up sleeping until a second period occurs. This is solved by using runtime->twake as the number of samples needed for a wakeup in addition to selecting the proper wait queue to wake in snd_pcm_update_state(). This requires twake to be non-zero when used by snd_pcm_lib_{read,write}1() even if avail_min is zero. Signed-off-by: Dave Dillow <dave@thedillows.org> Signed-off-by: Jaroslav Kysela <perex@perex.cz>

2010-06-23ALSA: usb-audio - Add volume resolution quirk for some Logitech webcamsAlexey Fisher
Some programs like Skype trying to set capture volume automatically. Normally it will tray, carefully step by step lover or higher, set the volume. In real word it work not really well, because devises and vendors lie about real audio settings. For example most Logitech webcams have 6400 or 3500 steps for capture volume. They do not tell that actual resolution is 384. So we have only 7 or 18 real steps. In this patch I set real resolution only for tested devices.

2010-06-21ALSA: usb/endpoint, fix dangling pointer useJiri Slaby
Stanse found that in snd_usb_parse_audio_endpoints, there is a dangling pointer dereference. When snd_usb_parse_audio_format fails, fp is freed, and continue invoked. On the next loop, there is "fp && fp->altsetting == 1 && fp->channels == 1" test, but fp is set from the last iteration (but is bogus) and thus ilegally dereferenced. Set fp to NULL before "continue". Signed-off-by: Jiri Slaby <jslaby@suse.cz> Acked-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2010-06-11ALSA: usb-audio: fix UAC2 control value queriesDaniel Mack
For RANGE requests, we should only query as much bytes as we're in fact interested in. For CUR requests, we shouldn't confuse the firmware with an overlong request but just ask for 2 bytes. This might need fixing in the future as it's not entirely clear when to dispatch 1-byte, 2-byte and 4-byte request blocks. For now, we assume everything is coded in 16bit - this works for all firmware implementations I've seen.
